β¦ Synopsis
The method for calculating solvent shifts on metal to ligand charge transfer (MLCT) and other electronic absorption bands involving charge transfer (e.g. ligand to metal and organic charge transfer) developed by Zeng, Hush and Reimers, henceforth named ZHR-SS, is reviewed. Also included are simple models for MLCT processes in mono-and di-metal complexes and a description of key aspects of modern electroabsorption spectroscopic techniques used to study MLCT transitions. The rationale behind ZHR-SS is summarized, as

The photoreactivity of coordination compounds in a MLCT excited state can be attributed to the nature of the oxidized metal and/or the reduced ligand. The general features of such photoreactions have been recently reviewed (A. Vogler, H. Kunkely, Coord. Chem. Rev. 177 (1998) 81). The present report
