O. Vahtras et al., AB-INITIO CALCULATIONS OF ELECTRONIC G-FACTORS BY MEANS OF MULTICONFIGURATION RESPONSE THEORY, Chemical physics letters, 281(1-3), 1997, pp. 186-192
A response theory algorithm is derived for calculations of the second-
order contribution to the electronic g-tensor, that is the combined pe
rturbation of the orbital Zeeman effect and spin-orbit coupling, for s
ingle-and multiconfiguration reference states. Sample calculations are
carried out for the NH and O-2 molecules, comparing with experimental
data and testing different parametrizations of the wavefunctions. (C)
