Hyperchem is available in both a standard and a "lite" version (Windows only) from Hypercube, Inc. A freely-distributed web browser plug-in supports manipulable 3-D views of molecules generated by Hyperchem. One of the strengths of Hyperchem is that it can be driven with internal scripts as well as DDE/OLE interaction with other Windows programs. Hyperchem reads PDB (ENT) files as well as its own HIN format files.
UV and IR spectra are presented as spectral displays and individual vibrational modes are animated. Molecular orbitals may be displayed as two-dimensional contour maps or as three-dimensional isodensity surfaces. Molecules may be presented as stick, ball and stick, space-filling, or dotted surface models. It includes molecular mechanics using several force fields, together with semi-empirical and ab initio quantum mechanical calculations.
HyperChem is a commercial molecular modeling program for Windows that is easily accessible to beginning students.
