The single crystal of N-Acetyl-L-alanine (NALA) has been synthesized by slow evaporation growth technique at ambient temperature using aqueous medium. The unit cell parameters of NALA crystal were identified using single crystal XRD analysis. The various functional groups in the crystal can be identified by FTIR analysis. The Ultraviolet-visible analysis used to prove the cutoff wavelength 231 nm of the crystal, Urbach energy calculated value of 0.11 eV and various optical constant values supports the NLO nature of NALA crystal. Wemple-DI Domenico model used to determine the various single oscillator parameters. Surface analysis and the various elements present in this NALA crystal is proved by SEM with EDAX analysis. Vicker micro hardness studies carried out to prove the stability of the crystal. The SHG studies proves the 1.4 times greater efficiency of NALA crystal than the KDP. Thermal stability of the crystal is proved by TG and DTA analysis. Glass transition (Tg) temperature proved by DSC analysis. Thermodynamic parameters elucidated by using the Redfern method.
