Natural Bond Orbitals (NBO), Natural Population Analysis, Mulliken Analysis of Atomic Charges of L-Alaninium Oxalate.

The Fourier Transform Infrared and Raman spectra of the L-Alaninium oxalate (LAO) have been recorded and analyzed. The fundamental vibrational wave numbers intensities of vibrational bands and optimized geometrical parameters of the compound were evaluated using DFT (B3LYP) method with 6-31+G(d,p) basis set. Natural Bond Orbital (NBO) and Natural Population Analysis (NPA) analysis for the LAO compound was carried out. Mulliken population analyses on atomic charges were also calculated.
