These volumes cover the structure and bonding (VBT, eFT, and MOT), stability and reactivity, spectral and magnetic properties of metal complexes in depth. Kinetics and reaction mechanisms of ligand substitution, electron transfer and photochemical reactions have been included. Magnetochemistry and organometallic chemistry have been covered. Applications of different spectroscopic techniques (Raman, IR, NMR, ESR, Mossbauer, UV-VIS, UV- PES, etc.) have been discussed to widen the utility of the series. In developing the present extension, we have taken all the measures to retain the basic features of the existing title.
