Abstract

The ORCA tool allows the user to perform ab initio simulations on molecular systems. The levels of theory range from post-Hartree-Fock methods to density functional theory including various functional and basis sets. The tool allows geometry optimizations with or without constrains, normal modes analysis and automatic ionization energy calculation.
