Selection of Molecular Matrix Elements from Atomic Data. III. 3d, 4s, and 4p Orbitals for Na, Mg, Al, Si, P, S, and Cl

Abstract

A modification of the method of Cusachs and Reynolds has been used to derive valence‐state ionization potentials for the 3d, 4s, and 4p orbitals of third‐row elements. For a fixed ionic charge, these VSIP are found to vary linearly with atomic number.
