Bn. Plakhutin, INTEGRAL INVARIANTS FOR HIGH-SYMMETRY OPEN-SHELL MOLECULES - 2 - ENERGIES OF SPECTROSCOPIC STATES, Journal of structural chemistry, 39(2), 1998, pp. 147-157
A method for calculating the energies of electronic states arising fro
m a degenerate open shell gamma(N) in terms of integral invariants H-k
(gamma, gamma) is presented. The calculation proceeds from expansions
for the electron repulsion integrals [m (m) under bar\n (n) under bar]
on degenerate orbitals of gamma symmetry in terms of H-k(gamma, gamma
). The energies of states for the gamma(N) electronic configurations w
ith dim gamma less than or equal to 3 (e(N) and t(N) configurations) a
re tabulated.
