Chemistry enhanced podcasts, Imperial College London.

Audio and video podcasts from undergraduate lecture courses given in the Chemistry Department. The audio materials are annotated as "enhanced" Podcasts with full lecture notes, handouts, and linked to rotatable/and or animated 3D models (of molecules, their vibrations, and their molecular orbitals. Requires Java) and to much original literature.
