The information of the crystal structure is a necessary pre-requisite for the understanding of materials, the knowledge of the electronic structure is of primary importance for investigating the optical, magnetic and spectral properties governed by the chemical bonding. First group transition metal ions form convenient probes for the study of the relevant properties of the materials. Spectroscopy is a powerful, simple and accurate tool to unravel the mysteries of electronic structures through these probes. Optical absorption and EPR studies are extensively used for exploring the interesting behaviour of transition metal doped crystals. This book presents the results of the investigations carried out on the optical absorption and electron paramagnetic resonance of transition metal ions in solids. The main objective of the study is to investigate the splitting of the energy levels of the transition metal ions doped into zinc potassium phosphate hexahydrate ZnKPO4. 6H2O (ZPPH) crystals and there by ascertain the site symmetry of the dopant ions. It also forms a definite contribution to the existing knowledge of the transition metal ion spectroscopy.
