Oy. Nikitin et Bk. Novosadov, CONSTRUCTION OF BASIS-SETS OF HYBRID ATOMIC ORBITALS FOR DESCRIBING THE NONEQUIVALENT BONDS OF AN ATOM WITH 4 NEIGHBORING ATOMS (SP(3) HYBRIDIZATION), Journal of structural chemistry, 36(6), 1995, pp. 887-892
Methods for constructing the basis sets of sp(3) hybrid atomic orbital
s for atoms surrounded with four neighboring atoms are discussed in de
tail. The results obtained are generalized as a theorem of sp(3) hybri
dization. A general method is proposed for constructing basis sets of
orthogonal sp(3) hybrid atomic orbitals for atoms with distorted tetra
hedral environments.
