Deactivation of biacetyl triplets by cyanocobaltate(III) complexes [PDF]
, 1972 The rate of electronic energy transfer from biacetyl triplets to Co(CN)_(5)(X)^(n–)(X = CN^–, MeCN, pyridine, N_(3)^–, H_(2)O, or SCN^–) is strongly dependent on the energy of the first spin-allowed d–d transition of Co(CN)_(5)(X)^(n–), and (for X = CN^–,
