Hi Bob et al,
This looks very interesting.
Could the energy plot for rotation of a methyl group be extended to show an interactive energy graph for any change in conformation? In the past I have used QuickTime movies from Spartan to display this but it would be much nicer to use Jmol.
e.g. Substituted cyclohexanes http://www.chemtube3d.com/EliminationE2regioselectiveA.html Diastereoisomer A and B links towards the foot of the page.
One way might be to perform an energy calculation on every frame of an .xyz sequence and display the results as in Bob's energy graph.

All the best

Nick

This script illustrates some very hot new capabilities of Jmol -- rotation of a methyl group; calculation of the energies of the rotatmers and display of the energy using a bar graph and echo text; clicking on a drawn line gets picked up as a Jmol script callback (no JavaScript here!) to rotate the structure to its corresponding rotamer.
