CRYSCOR is a program performing electronic structure calculations for 1D-, 2D- and 3D-periodic non-conducting systems at the correlated level (presently local second order Møller-Plesset Perturbation Theory - LMP2).

  • It uses the Hartree-Fock solution provided by the periodic LCAO-code CRYSTAL.
  • The local correlation scheme is similiar to that applied in the corresponding molecular techniques, e.g. in the MOLPRO package.
  • Two-Electron integrals are efficiently calculated using the density fitting technique (for the close-by pair distributions) and the multipole approximation (for the distant pairs).
  • The Dual Basis set scheme allows for an expansion of the virtual space with respect to that used in the reference HF calculation.

Precompiled serial executables are available for Unix/Linux/MacOSX platforms
