✦ Synopsis

Electron paramagnetic resonance studies of molybdenyi doped NH4Br crystals were made at room temperature. The resonance due to even isotopes of MO and the hyperfinc interaction due to g5*g7hfo is observed. The angular variation of the spectrum is studied in the crystallographic (001) plane. The symmetry a..es of the magnetic complexes are found to be along (LOO), (010) and (001) directtons of the crystal. The spectra arc analysed usmg a spin hamiltontan corresponding to tetrdgonal symmetry. The spin hamiltonian parameters indicate the formation of a stable [h!oOCls ] *complex io the lattice. The ligand spin orbit effects on g and A vakm is discussed. The spin hamiltonian parameters are correlated with the ligand properties like electronegativity, covalent nature, etc.
