Structure and molecular bonding parameters from ESR spectra of some schiff bases vanadyl ion complexes

الملخص EN

The electron spin resonance spectra of vanadyl ion complexes of N,N',N'',N'''- Bis(benzil) azomethine Bis(1,2-ethylene diamine) and N,N'-Bis(benzil) azomethine 1,2- ethylene diamine have been studied in solution at room temperature and frozen glasses.The spectra have been analyzed and the components of the g tensor and hyperfine tensors of complexes have been obtained.The unpaired electron is in the antibonding orbital (B2g).The spin Hamiltonian parameters have been equated to atomic orbital coefficients in some of the molecular orbital involved in bonding in these complexes.
