XChemEdit Version 0.93

XChemEdit is a multipurpose graphics package; it can draw and edit three-dimensional chemical structures, serve as a graphical interface to the BOSS, MCPRO and popular quantum mechanics programs, display molecular orbitals and electron densities, animate vibrational modes, compute thermochemical properties, manipulate a variety of common document formats such as Encapsulated PostScript (EPS) and FrameMaker, and generate graphics for publications. Chemical structures are constructed by importing atomic coordinates from common chemistry file formats such as Cartesian and PDB, or by using templates predefined in the program. Molecules can be represented in several alternative forms such as wire-frame, spoke, ball and stick, space-filling, and van der Waals and viewed in mono or stereo mode.

XChemEdit 0.93 includes many enhancements and new features including energy minimizations with the OPLS-AA force field and display of molecular orbitals from MOPAC93 output.
