Sažetak The Half-Projected Hartree-Fock model (HPHF) is proposed for determining open shell singlet states. Some properties of the HPHF wave function are reviewed in order to discuss its application to determining excited states of medium size molecules. A calculation procedure similar to that of the UHF method is described. Some results for the methylene biradical and formic acid are presented. The HPHF model is found to be useful for determining the lowest excited states.
