Where can I find a gif of the caffeine molecule?

Caffeine = 1,3,7-Trimethylxanthine

A different view of the caffeine molecule.

The Department of Chemistry at Jamaica of the University of Western Indies has made available an avi and an mpeg of a rotation of the caffeine molecule, among other molecules and chemical processes. The index page contains more information and the links to the clips.

Theobromine is also a common component of coffee, tea, chocolate, and mate (particularly in these last two).

Theophylline was once thought to be a major component of tea.This is not correct. Tea contains significantly more amounts of caffeine than of theophylline.
