title: Crystal growth and vibrational spectroscopic studies of the semiorganic non-linear optical crystal--bisthiourea zinc chloride.
abstract: The semiorganic non-linear optical crystal bisthiourea zinc chloride (BTZC) was grown by mixed solvent slow evaporation technique. The solubilities under various solvents in different proportions have been studied. Vibrational spectra were recorded to determine the symmetries of molecular vibrations. The observed Raman and infrared bands were also assigned and discussed. The optical transmission spectral study was also carried out. The property of second harmonic generation of BTZC was also verified.
