Chemistry 56 Spring 2003
Announcements: (4/28/03) Note that you can start Test 3 anytime from 7:30 a.m. to 9:00 a.m. on Thursday.
(4/21/03) · Test 3, covering (a) lectures from April 2 through whenever we finish magnetic resonance; (b) Chapters 16, 17, and 18; and (c) Problem Sets 7, 8, 9; will be during the lab time slot on Thursday, May 1 (as per the syllabus). As before, you will have 2.5 hours to work on the exam, and you can fill one side of a 8.5" x 11" piece of paper as a cheat sheet.
· However, there are some significant changes from the syllabus. We will not be covering statistical mechanics, nor will we have a tenth problem set, nor will we have a computational chemistry lab experience. However, after we finish Chapter 18, I will spend our remaining class time focusing on key concepts and techniques of computational chemistry.
· The final examination in the course (on Thursday, May 8, from
8:30 - 10:30 a.m.) will consist largely of the American Chemical Society's
standardized examination in Quantum Mechanics. (The test includes a few
questions on computational chemistry!) I will add a few essay and math questions
of my own devising.
See the bottom of the page for old announcements.

Old Announcements:
(4/1/03): (1) As I announced in class, I've postponed the due date for PS 6 until Tuesday (4/1) at 5 p.m. (If you already turned PS 6 in, you can get it back from me to work on it some more, if you want.). (2) Some comments on PS 6: (a) Problem 15.2--While group multiplication tables are not discussed in the text, Tom did discuss it in class. Come see me if you are still confused about this problem. (b) Problem 15.20. If you find that the representation is reducible, determine the symmetry species it spans.
(3) Test 2, covering Chapters 13, 14, 15; Problem Sets 4, 5, 6; and the b-carotene lab; will be on Thursday, April 3, during the lab time slot. (Note that, contrary to the course schedule, you are responsible for Tom's final lecture on Chapter 15 on March 31.) Just as with Test 1, you can fill one side of an 8.5" x 11" piece of paper with whatever information you want. No other reference materials will be allowed. Also note that I intend Test 2 to be mathematically more challenging than Test 1. Expect to draw on the differentiation and integration skills you have used to verify solutions of eigenvalue equations, find expectation values, etc.
(3/23/03): (1) Tom will do all the lecturing for Chapter 15 (on Monday, March 24, Wednesday, March 26, Friday, March 28, and Monday, March 31). (2) You will not meet for class during the lab time slot on Thursday, March 27. (3) Remember that Problem Set 5, on Chapter 14, will be due by 5 p.m. on Wednesday, March 26. (4) Test 2, covering Chapters 13, 14, 15; Problem Sets 4, 5, 6; and the b-carotene lab; will be on Thursday, April 3, during the lab time slot. (Note that, contrary to the course schedule, you are responsible for Tom's final lecture on Chapter 15 on March 31.) Just as with Test 1, you can fill one side of an 8.5" x 11" piece of paper with whatever information you want. No other reference materials will be allowed. Also note that I intend Test 2 to be mathematically more challenging than Test 1. Expect to draw on the differentiation and integration skills you have used to verify solutions of eigenvalue equations, find expectation values, etc.
(3/3/03) (a) The key for Test 1 is posted below. (b) The due date for Problem Set 4 (on Chapter 13) has been postponed until Friday. (c) We will meet for lab this Thursday at 8:30 a.m. in Olin-Rice 350. After finishing up Chapter 13 remarks, we'll talk about both the experimental and computational aspects of the lab. Each team need to bring a carrot to lab! (I will pass out instructions either on Wednesday or Thursday.) Your lab report will be due the following Friday, March 14.
(2/25/03) (1) See the PS 3 Key below. We plan on having your problem sets back to you tomorrow.
(2) A .pdf regarding Lapacian error in text.
(3) Your first test, covering Chapters 23, 11, and 12, and Problem Sets 1, 2, and 3, will be administered during the lab time slot on Thursday, February 27. You will have a maximum of 2.5 hours to work on the exam. I will let you use as a cheat sheet one side of an 8.5"x11" piece of paper filled with whatever information you want. (No other references will be allowed.) The majority of the exam will involve problem solving; however, there will be a few essay questions as well. You are not responsible for topics in Chapters 23, 11, and 12 that did not come up in class, in lab, or on the problem sets.
(2/24/03): (1) Remember than PS 3 is due tomorrow at noon. I will post the key for PS 3 right away, so people can use this as they start to prepare for Test 1.
(2/7/03): Please see the Revised Schedule for important comments about our XRD experiment with petrology.
(2/3/03) (1) We will meet with Karl Wirth's Petrology class on Wednesday
(2/5) and work with them on an XRD experiment starting Thursday morning (2/6).
(2) Problem Set 1 is due on Wednesday by 5 p.m. To
get reasonable values for angles in Problem 23.4, what you need to do is assume
that the
-->|1 cm|<-- mark in your textbook is 4.5 mm wide. Please
come talk with me if you have any questions about this.
(1/31/03) (1) We will meet with Karl Wirth's Petrology class on Wednesday (2/5) and work with them on an XRD experiment starting Thursday morning (2/6). (2) Problem Set 1 is due on Wednesday by 5 p.m. DO NOT USE the blow-Up of Fig. 23.60 I handed out last Wednesday as you do Problem 23.4. (For some reason, the -->| 1 cm | <--- mark on my blow-up of Fig. 23.60 is not at the same aspect ratio as the diffraction patterns themselves. I discovered this when I measured the arc length of the straight line on the top pattern. From what we discussed at the start of class on Friday, the straight line should occur when the cone of Bragg reflections flattens to a plane--at 2*theta = 90 deg, or theta = 45 deg. You will get very close to 45 deg if you use the diffraction patterns in your text. However, if you use the class handout, you will get roughly 35 deg. (My scanner must have screwed up the aspect ratio somehow.) So, measure the arc lengths on p. 810 of your text. Do not use my handout.)
