Abstract: Nonlinear optical Succinic Acid (SA) and L-Tyrosine Succinate Hydrobromide (LTSHB) single crystals were grown by slow evaporation technique. Single crystal X-ray diffraction (SXRD) revealed that both grown crystal belongs to monoclinic system. Optical behavior of the crystal was investigated using UV–Vis spectroscopy. The optical band gap energy have been determined as 5.48 eV and 4.31 eV respectively for SA and LTSHB single crystal. The presence of functional groups were identified by FTIR and Raman spectroscopic studies. The dielectric constant of the grown crystal was carried out as a function of frequency for different temperatures 308K, 328K and 348K, respectively. Thermogravimetric analysis (TG) of LTHSB were investigated at three different heating rates of 10°C /min, 15°C/min and 20°C/min to study the thermal decomposition and kinetics of the thermal decomposition of LTSHB using Kissinger, Flynn-Wall heating methods to found activation energies and the results are discussed.
