MOLDEN a visualization program of molecular and electronic structure
MOLDEN a pre- and post processing program of molecular and electronic structure
Molden is a package for displaying Molecular Density from
the Ab Initio packages GAMESS-UK , GAMESS-US
and 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.
It can write a variety of graphics instructions;
postscript, XWindows, VRML, povray, OpenGL, tekronix4014, hpgl, hp2392 and Figure.
Both Xwindows and OpenGL
versions of Molden are also capable of importing
and displaying of chemx, PDB, and a variety of mopac/ampac files and lots
of other formats.
Molden also can animate reaction paths and molecular vibrations. It can calculate
and display the true or Multipole Derived Electrostatic Potential
and atomic charges can be fitted to the Electrostatic Potential calculated
on a Connolly surface.
Molden also features an stand alone forcefield program ambfor, which can
optimise geometries with the combined Amber (protein) and GAFF (small molecules)
force fields. Atom typing can be done automatically and interactively from
within Molden, as well as firing optimisation jobs.
Molden has a powerful Z-matrix editor which give full control over the geometry
and allows you to build molecules from scratch, including polypeptides.
Molden was also submitted to the
QCPE (dead?) (QCPE619), allthough
Xwindows version is considerably running behind on the current one.
