        abstract = {The slow evaporation solution growth method was used to synthesise a nonlinear optical single crystal of 1-Carboxy-2-Methylpropan-1-Aminium Chloride 2-Azaniumyl-3-methylbutanoate using ethanol as solvent. The crystallisation process yielded a well-defined monoclinic system with centrosymmetric nature of P21 space group crystal, was revealed by comprehensive of single crystal X-ray diffraction analysis. UV-Vis-NIR spectroscopy, revealing a significant cut-off wavelength of the title compound. Urbach energy, which measures the width of the bandgap tails in semiconductors, showed a low value, indicating that grown crystal has excellent crystallinity, as well as a steepness parameter indicating sharp absorption edges. The electron-phonon interaction energy was estimated, offering insights into the coupling between electronic states and lattice vibrations. The grown material optical constants graphs such as the optical conductivity, extinction coefficient and refractive index were plotted with the function of optical absorption, wavelength and photon energy for assessing optical applications. Photoluminescence analysis demonstrated the excellent structural quality of the grown crystal. The grown compound electronic polarizability was estimated quantitatively, further advancing the understanding of its electro-optic properties. These comprehensive findings suggest that the compound has strong potential for use in nonlinear optical (NLO) devices.},
