MolDS is a semi-empirical electronic structure and molecular dynamics package.

Features includes:

* Semi-Empirical methods CNDO2, INDO, ZINDO/S, MNDO, AM1 and PM3
* Excited States via Single Configuration Interaction (CIS)
* Dispersion corrections to AM1 (AM1-D) and PM3 (PM3-D)
* Pairwise Distance Directed Gaussian (PDDG) correction to PM3
(PM3/PDDG)
* Single-Point, geometry optimization, Molecular Dynamics (MD),
Monte-Carlo (MC) and Polymer Molecular Dynamics (RPMD) type of
calculations
MolDS currently ships parameters for the elements H, C, N, O, and S.
