Abstract
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) 1997 Elsevier Science B.V.
