DMol3

DMol3 is a commercial (and academic) software package which uses density functional theory with a numerical radial function[1] basis set to calculate the electronic properties of molecules, clusters, surfaces and crystalline solid materials [2] from first principles. DMol3 can either use gas phase boundary conditions or 3d periodic boundary conditions for solids or simulations of lower-dimensional periodicity. It has also pioneered the use of the conductor-like screening model COSMO Solvation Model[3] for quantum simulations of solvated molecules and recently of wetted surfaces. DMol3 permits geometry optimisation and saddle point search with and without geometry constraints, as well as calculation of a variety of derived properties of the electronic configuration. DMol3 development started in the early eighties with B. Delley then associated with A.J.Freeman and D.E.Ellis at Northwestern University.[4] In 1989 DMol3 appeared as DMol, the first commercial density functional package for industrial use by Biosym Technologies now Accelrys. Delley's 1990 publication was cited more than 3000 times.[5]
