Abstract	which saturated solution prepared by dissolving equimolar ration of L-Alanine and acetic acid powder in water (distilled) was allowed to undergo slow evaporation. Single crystals of good transparency & optical quality (confirmed after employing below detailed characterization techniques) were extracted having sizes 11×7×1 mm3, 10×4×1.5 mm3 and 6×6×1 mm3 after an interval of 42 days. Structural properties of the LAA crystals like crystallinity and presence of various functional groups were confirmed by using powder X-ray diffraction technique and FTIR spectroscopic technique. Optical properties like UV cutoff wavelength value (observed at 232 nm) and optical energy bandgap value of 5.16 eV were determined using UV-Visible spectroscopic technique.
