In August of 2000, Advanced Chemistry Development (ACD) released the free all-purpose chemical drawing and graphics software ChemSketch; recently, ACD announced its 150,000th download. The software allows users to "click and draw molecules, ions, stereobonds, text, polygons, arrows, and do automatic calculation of Molecular Weight and formula and see estimates of density, refractive index, molar...

The Chemistry-Based QuickTime, Shockwave Flash, GIF Animations, and Streaming Audio Web site is provided to "support the teaching of concepts in chemistry in freshman through graduate level courses." Dr. Thomas Chasteen's site offers links to multimedia files related to chemiluminescence, gel electrophoresis, how a grating works, gas chromatography and mass spectrometry, titrations, atomic...

Produced by Thomas Poon at Claremont-McKenna College and Bradford Mundy at Colby College, the Poon-Mundy computer animations are Macromedia Shockwave movies created to assist students with organic chemistry. Students can observe the production of hybrid atomic orbitals, a simulation of a mass spectrometer, the pyramidal inversion in amines, and much more. With sixteen colorful animations covering...

From the University of Oxford Department of Chemistry comes the Pre-University Chemistry Course teaching material Web site. This multimedia learning resource is based on the book Chemistry, Matter and the Universe by Richard E. Dickerson and Irving Geis, and contains more than twenty topics. Users can learn about atoms, molecules, moles, particles, waves, heat, energy, and more through various...
