First Time

The recently developed approach to auxiliary density perturbation theory (<em>J. Chem. Phys.</em> <strong>2008</strong>, <em>128</em>, 134105) for the purpose of calculating molecular properties is here extended to include open-shell systems. Both unrestricted and restricted formalisms are considered. A linear equation system, twice as large as the auxiliary function set is obtained in both cases. For the first time, the formulation for auxiliary density perturbation theory for restricted open-shell formalism is derived.
