Volume 6 covers magnetochemistry and magnetic properties of metal complexes; structure, bonding and reactivities of organometallics including metal carbonyls and nitrosyls, organometallics as catalysts. Volumes 4-7, which are in continuation of the existing Volumes 1-3 of the book, 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, isomerisation, electron transfer and photochemical reactions have been included. Topics of magnetochemistry and organometallic chemistry have been covered. Applications of different spectroscopic techniques (Raman, IR, NMR, ESR, Mossbauer, NQR, Mass Spectrometry, UV-VIS, UV-PES, etc.), theory of errors and statistical treatment of data have been discussed to widen the utility of the series.
