This figure shows how the electron density and van der Waals surfaces can be used to visualize steric strain. See this post on how to make such pictures and this post on how to make an interactive version such as the one shown below.

Jan,
Great Blog, Great work!
Question, where do you have jmol hosted so you can post jmol scipts in your blog post or web page? Do you host it locally or are you using something like google app engine to run it?
Thanks,
Jonathan
Jonathan - thank you!
I host Jmol locally, together with the necessary coordinate files.
Have a look at the page source for this page, which I made as a test before using it in the blog. Everything in the header is put in a gadget on the blog.
do you know if that completely planar structure is a minimum or does it have an imaginary torsion frequency?
it's a minimum - no imaginary frequencies.
