I’d just like to note that Ian McC and I figured out how to hook up music to the overhead speakers in the downstairs computer lab; it has a pretty good bass too. So if anyone wants to join me for a study party while getting through this modeling problem set…I am blasting loud music and working on Spartan modeling.

Tomorrow’s lecture will contain additional info about 1) breaking MOs down into smaller pieces, 2) Frontier MOs and transition states, 3) Frontier MOs and reactivity predictions. So … if you get frustrated during tonite’s marathon session, pull the plug and bring your questions to class tomorrow.
Reminder: Monday office hours 11-11:30 and 3-4

Was HW 5 handed out today and I just missed it?

Sorry about the confusion re: HW 5. All I can say right now (late PM on Monday) is HW 5’s status is currently in limbo. Same goes for the rest of this week’s schedule.
Unfortunately, a bunch of off-campus meetings and appts fell into this week (Mon-Tues-Wed) so I’ve got my hands full. I’ll try to clarify the HW situation tomorrow.

I’ve modified HW #5 and posted the revised assignment. There is *no change* in the assignment itself. However, I said that I would attach reading instructions for paper #5 and I have changed my mind about that. Instead, exam #1 will contain some questions that refer to paper #5. See HW #5 for details.

I’m a little confused by what you want in terms of writing for problem 3 on problem set 5.
Alan // March 2, 2009 at 1:52 am |
HW #5, problem #3 – no writing is needed. Just an orbital mixing diagram. MO energy levels on the left (butadiene). MO energy levels on the right (ethylene). MO energy levels in the middle (transition state). Lines connecting middle to sides show which reactant MO mix to make transition state MO.

I’m having difficulty getting the ZPE energy correction to work reliably on Spartan on problem #3, pset #6. Any tips?
Alan // March 22, 2009 at 11:04 pm |
I’ve received two questions about ZPE corrections: Connie’s comment and a separate email from Ian. I’ll create a post on this topic.

HW #7 correction. Problem #3b should say “diester” and not “diketone” (both times). I’ll post a corrected assignment after dinner.

I have add two pages of drawings and comments to the answers for HW #6. *Many* of your orbital array drawings were fine, but when the going got tough, the drawing quality/detail sometimes suffered. Just what anyone would have predicted. So look at my drawings and make sure that you understand what is required in this respect.
