Old Announcements:

(4/28/08) (1) Here is the Test 3 preview sheet.  The test is this Thursday, from 8:30 to 11:30 a.m., in OR 350.  You may prepare a one-page cheat sheet, as usual.  (2) Your final, an ACS multiple-choice exam covering material also covered by the three unit tests, will be on Monday, May 12.  On May 12, you will also turn in Problem Set 6, covering electronic spectroscopy and statistical thermodynamics.  More details by this Friday.(4/19/08) Please note our agenda for this coming week:

Wednesday
o End of material for Test 3
o Problem Set originally due on Monday 4/28 is cancelled

Thursday
o Meet at 8:30 a.m. in OR 350
o Do Chapter 14 (electronic spectroscopy)
o Fill out IDEA course evaluation forms

Friday
o Experiment 3 due this Friday by 4:00 p.m.
o Start Chapter 16 (statistical thermodynamics)

(4/15/08): (1) Remember that Problem Set 5 is postponed until this Friday, April 18.  (2) There is a typo in Experiment 3: In Equation 6, the factor in the denominator, wavenumber, should be squared.  The corrected version is here.  (3) I am postponing the due date for Experiment 3 to Friday, April 25.

(3/30/08): (1) Here is the Test 2 Preview Sheet.  Test 2 is this Thursday, in Olin-Rice 350, starting at 8:30 a.m.  You can pick up your graded PS 4 from the table outside my office.

(2) Here is next week's schedule:

(3/11/08): (1) Homework will now be worth 25% of your final grade, and the three unit tests will be worth 45% of your final grade.  (The student vote was unanimous!)  (2) We will not have time to talk about group theory (Chapter 12) this semester.  As a result, I will be canceling Experiment 3 (Huckel MO Theory Calculations), since this is based heavily on group theory.  Emily, Nikki, and Becca can attest to the fact that juniors will have the privilege of learning and using group theory extensively to describe the electronic structure of polyatomic molecules in Advanced Inorganic Chemistry next semester!

(2/25/08): Please note the following about Test 1:

* It will be this Thursday, starting at 8:30 a.m., in Olin-Rice 350.
* You will have either 2.5 or 3 hours to work on the exam (I will announce this on Thursday morning).
* You may bring a cheat sheet--an 8.5" x 11" piece of paper filled front and back with whatever information you would like.
* The exam booklet will provide possibly relevant constants, but not necessarily equations.
* You are responsible only for what we covered in lecture (through the start of class on 2/20), Experiment 1, and Problem Sets 1 and 2.
* In addition, you are not responsible for 2D rotation on this exam.
* Expect a mixture of calculations and short essay questions.

Good luck as you study, and please come see me or e-mail me if you have any questions.

(2/1/08): Remember that I've postponed (indefinitely) Problem #7 (Atkins and de Paula Problem 8.14) on Problem Set 1.  The other assigned problems are still due on Friday, February 8.
