โฆ Synopsis
Characteristics of the electronic excited states of transition-metal complexes are reviewed, Attention is focussed on the experimental means of ~dentifying the orbital natures ef the emitting manifolds. Two new criteria for distinguishing among excited triplet terms are enunciated: (a) the profile of the phosphorescence lifetime vs. the temperature in the range 77-4 K, and (b) the functional dependence of the phosphorescence decay rate on an external
