title: Single crystal EPR studies of an organic NLO material: methyl-p-hydroxy benzoate.
abstract: Single crystals of an organic nonlinear optical (NLO) material methyl-p-hydroxy benzoate (MHB) were grown by solvent evaporation technique. EPR spectra were recorded for Er3+: MHB and gamma-irradiated MHB at room temperature at X-band frequencies. The angular variation studies of the spectra were observed and the principal values of g were determined. The grown crystals were characterized by single crystal X-ray diffraction studies.
