Investigations on the vibrational spectroscopy and on the thermal behaviour of bis-thiourea zinc acetate—BTZA

Single crystals of bis-thiourea zinc acetate (BTZA) for use as a non-linear material have been grown using solution growth technique under optimized growth conditions. Investigations have been carried out to assign the vibrational frequencies of the grown crystals. FTIR and Raman spectra were taken and compared to evaluate the molecular vibrational properties of the grown crystals. Thermo-gravimetric analysis (TGA) and differential thermal analysis (DTA) have been carried out to understand the effect of temperature-influenced weight loss and on the endothermic and exothermic characteristics of thermo-gravimetric analysis (TGA).
