Abstract
Results of ab initio SCF calculations on phospha-alkynes R-C≡P with R=H. CH3, NH2, OH. F and Cl are reported. The geometries were optimized by the force method with analytical gradient employing double zeta (DZ) basis sets. Various molecular and one-electron properties are calculated with double zeta plus polarization functions (DZ + P) and compared with experimental ones. The effect of substituents is analysed in terms of computed properties.
