The ground state wave function of VO2+ ion doped in different single crystals is estimated with the help of admixture coefficients due to spin orbit coupling. The bonding parameters (K-parallel to and K-perpendicular to) choosing the different parametric angle beta are also determined. The interpretation of g factor using the Stevens method of molecular orbital for octahedral complex containing transition metal ion is given. The value of K-perpendicular to should be less than 0.06. The hyperfine interaction parameter P and Fermi contact term K are also calculated. (C) 2009 Elsevier B. V. All rights reserved.
