Molecular Modeling software: I use ChemWindows available from Bio-Rad. It comes with a simple, quick 3-D modeling program (SymApps) for small molecules to medium-sized (ie, not proteins, DNA, etc.). Their web site is www.bio-rad.com but it is very difficult to find just how to order it. This is what I have posted on my course web site for my students: This company was bought by Bio-Rad and Bio-Rad has an incredibly LAME Web site but if you can actually find where to buy this software, it is worth it. This is the program that I use. Powerful set of programs allowing standard, wireframe, stick, stick-and-ball, space-filling and animated molecular modeling. Handouts in class and molecular models on this web site are constructed with ChemWindow Suite 5.1, they are up to 6.0 now.
