✦ Synopsis


The use of hierarchical orthogonality restrictions in handling the nonorthogonality problem which arises when spin-coupled wave functions are employed to describe the electronic structure of extended molecules is investigated.

Theoretical calculations performed using the coupled Hartree-Fock perturbation theory (CHFPT) show that the MNDO approximation is superior to INDO and MIND03 in computing nuclear spin coupling constants between directly bonded carbon and hydrogen in polysubstituted methanes, HCXYZ. The CHFPT-MNDO pr
