The MOLFDIR package

The MOLFDIR code is a quantum chemistry code for molecular Fock-Dirac many-electron calculations and correlation calculations to account for electron correlation. It was developed at the university of Groningen. The MOLFDIR program package consists of separate FORTRAN programs (MOLFDIR, RELONEL, RELTWEL, MFDSCF, ROTRAN, TMOONE, GOSCIP, DIRRCI, RELCCSD and four other programs GENBAS, CALDENS, PRTRAN and PROPAN) that communicate by means of data files. The input data may be grouped on one file because NAMELIST type input is required for all modules. More information can be found in:
