The "Molecular motions..." pages are mainly designed as visual aids for students. The idea was suggested by Per Jacobsson, to whom I address my sincere appreciation.

Molecular simulations done with semi-empirical quantum mechanical simulations program suit MOPAC. Many thanks to the main author and countless contributors, who made available both the code and excellent descriptions of the physics behind.

Animations done with Jeffrey Gosper's Re_View.

Ray traced images rendered with Persistence of Vision raytracer.

Also many thanks to Irfan Skiljan for his superb image viewer/editor IrfanView.
