Office hours for the remainder of finals week are
9:00-10:00 AM and 1:00-2:00 PM both Thursday and Friday, and by
appointment (limited availability). I am trying to get labs graded
so that you will have additional feedback as you write your final two
reports. To do that I need large blocks of uninterrupted time. As I finish grading things they will be placed in the box outside my door. Exam 2 is already there and labs are being placed there as I finish them. Labs are being done in the order received. The absolute deadline for all course materials to be handed in is 5:00 PM Friday. I will check my mailbox and my office after the senior awards ceremony on Friday (about 6:30 PM), and anything not handed in by then will not be accepted. However, if you have extraordinary issues that prevent you from meeting this deadline, e-mail me. I expect to finish grading everything for the lecture course by May 10 and the laboratory course by May 13 (at the latest). I will enter grades into Banner within 24 hours of when I finish grading. Your grades will be available on Banner as soon as the system is "rolled" and the University releases them. |

The take-home portion of Exam 2 is available in PDF
format by clicking here. The
Excel file containing the wavenumber of CO's IR spectrum may be obtained
by clicking here. Relevant problems and exercises from the book are as follows. I have a few more next week (won't be on the exam, but you need to know how to do these for the final). Exercises: 11.1-11.7 (14.5-14.11), 11.9 (14.13), 11.10 (no corresponding problem in the 7th edition), 11.13a (14.16a), 12.4 (15.8), 12.12 (15.16), 12.13 (15.17), 12.14 (15.18), 14.1 (17.6), 14.4 (17.7), 14.5 (17.10), 14.7 (17.12), 14.11 (17.16). Problems: 11.10 (14.11), 11.12 (no corresponding problem in the 7th edition), 11.14 (14.14), 14.21 (17.22). |
| 04/20/09 | The take-home portion of exam 2 will be available Wednesday, April 22, which means that Exam 2 will be pushed back until Wednesday, April 29. I will have problems from the book for you to work before this exam later today, or tomorrow morning at the latest. |
| 04/15/09 | Click here to obtain Take-Home Quiz 3 in PDF format. It is due Friday in class. |
| 03/30/09 | All web pages are up, except group 6 (I will talk with them later). Somebody picked up the wrong handouts this morning. I have three Vibrational Structure of I2 handouts left (group 5) and one of Keto-Enol groups (group 1) didn't get their handouts. If you have the wrong ones, please return them to folder outside my office ASAP and get the correct ones. You will not be allowed to change which exercise you do simply because you picked up the wrong handouts! |
| 03/27/09 |
Here are the assignments for the last laboratory
exercise. Group 1's and group 5's web pages are up and their
handouts are outside my door. I hope to have the other groups done
either tomorrow (if I can't get to Columbia) or Sunday (if I can get to
Columbia). Group 1: Variation of K for the Keto-Enol Tautomerism of β-Dicarbonyls (includes both NMR spectroscopy and computational work) Group 2: Magnetic Susceptibility by NMR Group 3: Blackbody Radiation Group 4: IR Spectrum of Ozone Group 5: Vibrational Structure on the B 3Πu+ ← X 1Σg+ Transition of I2 Group 6: Computational Chemistry of Conjugated Dyes |
| 03/18/09 | Click here for a PDF version of Take-Home Quiz 2. Don't forget that there will be at least one more Take-Home Quiz after this one as well as at least four more quizzes and Exam 2. |
| 03/16/09 |
Problems and exercises for atomic structure and
atomic spectroscopy are listed below. Questions over material
covered before break may be on the week's quiz, although older material
may be stressed more (i. e., vibrational spectroscopy of molecules).
These problems will be good for the next two or three quizzes, so pace
yourself and do the problems associated with a topic after I have
covered a topic in lecture. Exercises: 10.1 (13.5), 10.2 (13.6), 10.6 (13.10), 10.8 (13.11), 10.9 (13.12), 10.10 (13.13), 10.12 (13.15), 10.14 (13.17), 10.15 (13.19), 10.18 (13.22), 10.19 (13.23). Problems: 10.2 (13.5), 10.3 (13.3), 10.6 (13.6), 10.9 (13.9), 10.14 (13.16), 10.18 (13.9), 10.23, 10.25 (the last two problems have no corresponding problems in the 7th edition). |
| 03/02/09 |
Another couple of clarifications for post-exam 1. In
question 5a do the derivation for a linear molecule and in question 7 do
the calculation only for the Stokes lines (note that you already know
the splitting for the Stokes lines). Don't forget to be working problems for the quiz on Friday! You should focus your attention on the simple harmonic oscillator problems from chapter 9 and the vibrational spectroscopy problems from chapter 13. These are as follows. Simple harmonic oscillator: exercises 9.8 (12.10), 9.9 (12.11), 9.10 (12.12) and 9.15 (12.16) and problems 9.2 (12.2) and 9.16 (12.16). Vibrational spectroscopy (some of these also deal with the simple harmonic oscillator): exercises 13.16 (16.19), 13.17 (16.20), 13.19 (16.22), 13.20 (16.23), 13.22 (16.25), 13.23 (16.26), 13.26 (16.29) and problems 13.12 (16.12), 13.15 (16.15) and13.20 (16.21). |
| 03/01/09 | Click here to view the full rules for the post-exam portion of exam 1. Click here to obtain a copy of the post-exam as a PDF file. I've added clarifications for problem 7 (it should be for rotational Raman spectroscopy, for an obvious reason) and for problem 9 (both states should be taken as singly degenerate) to this PDF file. Be sure to make these changes! I will post additional updates as needed. |

This is what I hope is the last typo from the
take-home. Again in problem 4, the Bohr magneton units should be
cm-1·T-1 (1 T = 104 G).
Also, there is in an error in the book. The integral of sin2(ax) should be  .
|
| 02/25/09 | Yet more typos from the take-home. The first is in problem 4 on page 10, second paragraph. The matrix element should match the two given wavefunctions. The second is in problem 3d. I omitted that the temperature is at 300.0 K. These have been corrected in the online PDF version. |
| 02/21/09 | Another typo from the take-home. Question 3c should read "The instrument on which these data were obtained didn't have a sufficiently high resolution..." This doesn't really change the problem in any way, but the PDF version available below has been updated to reflect the change. |
| 02/20/09 |
Since I didn't get as far as I thought I would, I am
going to cut off the material on Exam 1 at what we covered through today
(up through rotational spectroscopy, including group theory, basics of
quantum mechanics and the rigid rotor). The simple harmonic
oscillator and vibrational spectroscopy will be on Exam 2.
I've discovered my first typo for the take-home portion of Exam 1. The last sentence in question 4b should read "Why is D called a zero-field splitting parameter?". You may download the corrected version of the exam as a PDF file by clicking here. |

For the next quiz (and for Exam 1) you will need to
do the following problems and exercises. I've divided them up by
topic so that you can know when we've covered them in lecture. For
the quiz on 2/20/09 we will have covered the particle in the box, basic
aspects of spectroscopy and parts of the rigid rotor. The week of
2/16/09-2/20/09 we will finish rotational spectroscopy and start on the
simple harmonic oscillator. The week of 2/23/09-2/27/09 we will
discuss vibrational spectroscopy. Exam 1 will cover at least
through the simple harmonic oscillator, and perhaps more. General spectroscopy and group theory applications: exercises 13.1 (16.4), 13.2 (16.5), 13.3 (16.6), 12.3 (15.7) and 12.4 (15.8), and problem 13.13 (16.3). Particle in a box: exercises 9.1 (12.4), 9.2 (12.5), 9.5 (12.7), 9.7(12.9), and problems 9.1 (12.4) and 9.8 (no corresponding problem in the 7th edition). Rigid rotor: exercises 9.16 (12.17), 9.18 (12.19) and problems 9.3 (12.3), 9.4 (12.4), 9.20 (12.18), 9.24 (12.20) and 9.28 (12.24). Rotational spectroscopy: exercises 13.6 (16.9), 13.8 (16.11), 13.9 (16.12) and 13.12 (16.15) and problems 13.5 (16.5), 13.7 (16.7), and 13.8 (16.8). Simple harmonic oscillator: exercises 9.8 (12.10), 9.9 (12.11), 9.10 (12.12) and 9.15 (12.16) and problems 9.2 (12.2) and 9.16 (12.16). Vibrational spectroscopy (some of these also deal with the simple harmonic oscillator): exercises 13.16 (16.19), 13.17 (16.20), 13.19 (16.22), 13.20 (16.23), 13.22 (16.25), 13.23 (16.26), 13.26 (16.29) and problems 13.12 (16.12), 13.15 (16.15) and13.20 (16.21). |
| 02/01/09 | For the quiz on 2/13/09 do exercises 9.1 (12.4), 9.2 (12.5), 9.5 (12.7), 9.7(12.9), and problems: 8.4 (11.4), 8.18 (11.18), 8.19 (11.19), 8.20 (11.20). I will add more problems to this list depending on how far I get in lecture. |
| 02/01/09 |
Exercises for the next quiz: 8.1-8.10, 8.12, 8.13
(11.4-11.20) are basically plug-and-chug and you should be able to do
any of them, but don't waste your time doing all of them.
Exercises 8.11 (no corresponding problem in the 7th edition),
and 8.14 (problem 11.24) are important. Problems: 8.2 (11.2), 8.6 (11.6), 8.9 (11.10), 8.15 (11.15), 8.16 (11.16), 8.17 (11.17). Helpful hint: you need to be able to normalize a wavefunction and determine whether it is orthogonal. I may not have it on the 2/6/09 quiz, but it will appear soon. |
| 01/27/09 | Note some changes to the exercises for the next quiz given below. Exercises 12.3 (15.7) and 12.4 (15.8) will be for a later time. Sorry I didn't notice this earlier. |
| 01/24/09 |
Exercises for the next quiz: 12.1, 12.2, 12.5-12.11 (15.5,
15.6, 15.9-15.15
in the 7th edition). Problems for the next quiz: 12.1-12.3 (15.1-15.3 in the 7th edition). |

Here are the links to the CHEM 121 review problems
for basic
quantum mechanics,
covalent bonding, and
ionic bonding and the solid state. The answers are available
(quantum mechanics,
covalent bonding, and
ionic bonding and the solid state). My CHEM 121 lecture notes on
these topics are also available; click
here
to view. Remember that some of these questions, or ones similar to them, will be on the quiz next Friday. Material from the first week of lecture may also be included. |
