Concerning the absorption spectra of the ions M(bpy)/sub 3//sup 2 +/ (M = Fe, Ru, Os; bpy = 2,2'-bipyridine)
An electronic structural model, which includes spin-orbit coupling, is developed for the absorption spectra of the ions M(bpy)/sub 3//sup 2 +/ (M = Fe, Ru, Os; bpy = 2,2'-bipyridine). It is found that, even for Os, the excited states can be classified as singlets and triplets although there is considerable mixing between the pure spin states. Consequently, the luminescent excited states of Ru(bpy)/sub 3//sup 2 +/ and Os(bpy)/sub 3//sup 2 +/ are assigned as being states largely triplet in character. Explicit assignments of the absorption spectra for the complexes are proposed. The implications of the present treatment relative to other theoretical analyses are discussed. 8 figures, 7 tables.
