Molden software free download is a package for displaying Molecular Density and program of molecular and electronic structure from the Ab Initio packages GAMESS-UK , GAMESS-US and GAUSSIAN in Computational Chemistry. the Semi-Empirical packages Mopac/Ampac, it also supports a number of other programs via the Molden Format. Molden reads all the required information from the GAMESS / GAUSSIAN outputfile.
Molden is capable of displaying Molecular Orbitals, the electron density and the Molecular minus Atomic density. Either the spherically averaged atomic density or the oriented ground state atomic density can be subtracted for a number of standard basis sets. Molden supports contour plots, 3-d grid plots with hidden lines and a combination of both.
