ORCA
ORCA is a multi-purpose quantum-chemical software package. It features a wide variety of methods ranging from semi-empirical methods to density functional theory to correlated single- and multi-reference wave-function based methods. Environmental as well as relativistic effects can be taken into account. ORCA is the leading software tool in the calculation of spectroscopic properties of open-shell molecules.
