MOLDEN

Molden is a package for displaying molecular density from the Ab Initio packages Gamess and Gaussian and the Semi-Empirical packages Mopac/Ampac. Scripts have also been written to convert the output from other Ab Initio programs to Molden format (see link below). In addition, the Xwindows version of Molden can import and display chemx, PDB, and a variety of mopac/ampac files and other formats.

Molden has a flexible Z-matriz editor which allows full control over the geometry, and structures can be written in several different formats. The program can animate reaction paths and molecular vibrations, and can display molecular orbitals, electron density as contour plots, and 3-D grid plots. There is also an OpenGL version available which generates more user friendly plots via an external helper program.

Molden can write a variety of graphics instructions; postscript, XWindows, VRML, povray, OpenGL, tekronix4014, hpgl, hp2392 and Figure.
