This treatment of molecular and atomic physics is primarily meant as a textbook. It is intended for both chemists and physicists. ·It can be read without much knowledge of quantum mechanics or mathematics, since all such details are explained-. It h

Photoelectron spectra of p -benzoquinone and tetrafluoro- p -benzoquinone have been measured by He II up to 25 eV and interpreted using the semi-empirical MO method HAM/3. The order of the four highest occupied MO's has been obtained as n n π π fro

The interpretation of spectra of molecules by use of semi-empirical methods, of which SPINDO is an example, is usually possible for only one property of the molecule. If several properties of the molecules are used in the parametrization process the

By means of a comparison with the CNDO method we show that the HAM/3 formalism is a legitimate version of the SCF method. It is distinguished from the standard Roothaan-Hartree-Fock version of the SCF method by an unconventional exploitation of an in

An MO SCF theory for molecules has been developed starting from Slater's study of atomic shielding constants. Use of shielding “constants” which are functions of the nature of the shielded electron gives good total energies for a number of atomic

The electronic structures of HCN and DCN have been determined by examining high resolution He(I) photelectron spectra of HCN and DCN, He(II) photoelectron spectrum of HCN, and the electron impact energy loss spectra of HCN and DCN. The present invest

The 30.4 nm He(II) photoelectron spectra of fluorine(F2), of acetylene and diacetylene and their fluorosubstituted derivatives have been recorded. The use of He(II) radiation allowed the confirmation of the conjectured B∼2Σ+g state of the fluorine
