The Calculation of Coefficients of Coulomb and Exchange Integrals in Matrix Elements Involving Polar Singlet Structures


Starting from Pauling's rules for calculating matrix elements for covalent structures, it is shown how to extend the valence‐bond treatment to polar structures. Attention is called to the new types of integrals which are involved and simple procedures for evaluating their coefficients are described.
