Molcrunch
An atomic or molecular electronic properties computational package
...It provides Gaussian and Slater orbital support for SCF,
MCSCF, and orthogonal or nonorthogonal orbital CI calculations.
Its most sophisticated feature is a configuration
manipulation CI package that provides symmetry filtering, orbital occupation
selection, and a choice of many other wave function and/or basis characteristics. The symmetry filtering includes the ability to deal
directly with certain non-Abelian groups as well as all Abelian groups. Linear systems can be treated exactly within the full continuous
D-infinity-h or C-infinity-v groups.
