Results of Electron Paramagnetic Resonance (EPR) and Optical Absorption (OA) studies of VO2+ ion doped in Cadmium Ammonium sulphate Hexahydrate (CdASH) , which is is the only Tutton salt in which the metal ion belongs to the second long period in the periodic system, in the powder form have shown that in all these hosts a pentahydrate vanadyl complex VO(H2O)5 2+ doping the OA studies shows that these complexes reflect almost C4V symmetry. Correlating the optical and EPR data, the molecular orbital coefficients have been obtained and discussed. It has been concluded that both EPR and optical results are in conformity with each other.
