Dirac (software): Art & Overview

Dirac (named after Paul Dirac; own notation DIRAC) is a relativistic ab initio quantum chemistry program. The full name is Program for Atomic and Molecular Direct Iterative Relativistic All-electron Calculations, in short PAM DIRAC. It is capable of calculating various molecular properties using the Hartree–Fock, MP2, density functional theory…
