The crystals of N-acetylglycine (NAG) had been obtained through the gradual evaporation of an aqueous solution at room temperature. Single crystal X-ray diffraction analysis let out that the crystal associated to monoclinic system with centro symmetric space group P21/c. The lattice parameters are calculated to be a=4.8410(10) Å, b=11.512(2) Å, c =9.810(2) Å, α=90o, β=97.02(3)o, γ=90o and V=542.61 (Å)3. The primitive unit cell has 4 molecules. Vibrational spectroscopic analysis is reported on the basis of FT-IR and FT-Raman spectra recorded at room temperature. The crystal gives notable vibrational effect due to the presence of extensive hydrogen bond network. The UV-Vis studies have been carried out and the cutoff wavelength λ is observed to be 379 nm. The energy gap is calculated as 2.757 eV. The luminescence property has been examined by Photo luminescence spectrum. Thus in the existing study, structure-property correlation of n-acetylglycine molecule is investigated for future nonlinear optical purposes through experimental approach..
