OK, Wednesday we go 3D. Bring your models if you have them. The whole idea here is thinking about energy in terms of the 3-dimensional rotation about C-C bonds. It's the basis for much else that you will do in organic.


Suggest you take a peek at these for Wednesday.

You might not be able to view the following if you don't have the chime plugin installed for your browser. The file you need is

http://www.stolaf.edu/people/hansonr/tmp/npchime.dll

(select "save to disk" if you click on that link.)
If you have a PC, it goes in your Netscape "plugins" directory

usually C:\Program Files\Netscape\Netscape\plugins

or your Internet explorer plugins directory

C:\Program Files\Internet Explorer\PLUGINS

I don't know what the file is that you need for a Mac.
