Polarized Raman and infrared spectra of bis(thiourea)cadmium chloride, a novel semiorganic nonlinear optical crystal, were recorded to determine the symmetries of molecular vibrations. The observed Raman and infrared bands are assigned to molecular vibrations of thiourea, cadmium-sulphur and cadmium

β¦ Synopsis
Bis Thiourea Zinc Chloride (BTZC) a new semiorganic nonlinear optical material has been synthesized. The solubility studies have been carried out in the temperature range 30Β°-55Β°C. Single crystals of BTZC have been grown by slow evaporation of saturated aqueous solution at room temperature. The lattice parameters of the grown crystals have been determined by single crystal Xray diffraction technique. The UV-Vis-NIR transmittance spectrum has been recorded in the range 200 -2000 nm. The FT-IR spectrum has been recorded in the range 400 -4000 cm -1 and the spectral bands have been compared with similar thiourea complexes.
