Abstract

In current work, the experimental and theoretical investigation on glycine-glutaric acid (GGA) has been reported. Single crystals of GGA were grown by slow evaporation solution technique in an aqueous solution. Crystal structure and lattice parameters of GGA were confirmed by powder X-ray diffraction analysis. The ground and excited state properties of GGA were obtained within the framework of density functional theory. The calculated infrared spectrum and the S0→S1 transition energy were compared with the earlier reported experimental results and found in good agreement. HOMO-LUMO energy gap was calculated by using RHF/6-31G(d,p) and B3LYP/6-31G(d,p) level of theoretical calculations. Dipole moment of GGA obtained by RHF and B3LYP was found 11.84 and 10.87 D respectively.
