TL;DR: In this article, the generalized crystal field theory of Finkelstein and Van Vleck is augmented by the introduction of spin-orbit coupling and an attempt is made to account for both the spin-allowed and spin-forbidden dn, (n = 2, 8), spectral transitions of Ni(II) and V(III) complexes.

TL;DR: In this paper, a simple co-ordinative behaviour of bidentate figands is described, and the authors show that it is possible to construct dithiolene-like complexes with co-coordinated ligands.
