title: Synthesis and spectral characterization of acetophenone thiosemicarbazone--a nonlinear optical material.
abstract: Acetophenone thiosemicarbazone (APTSC) was synthesized. Solubility of APTSC was determined in ethanol and methanol at different temperatures. Single crystals were grown from ethanol by slow evaporation at room temperature. The grown crystal was subjected to FTIR, Laser-Raman and (1)H NMR spectral analyses to confirm the synthesized compound. Thermal properties were investigated by thermogravimetric and differential thermal analyses. High-resolution X-ray diffractometry (HRXRD) was employed to evaluate the perfection of the grown crystal. The range and percentage of optical transmission was ascertained by recording UV-vis-NIR spectrum. The third order nonlinear optical parameters (nonlinear refractive index and nonlinear absorption coefficient) were derived by the Z-scan technique.
