An extensive theoretical study on the molecular structure and vibrational analysis of 3-amino-4- methoxy benzamide (3A4MBA) was undertaken using density functional theoretical (DFT) method. The possibility of formation of intramolecular hydrogen bonding was identified from structural parameter analysis and confirmed with the natural bond orbital (NBO), molecular electrostatic potential (MEP) and natural charge analysis. The harmonic oscillator model of aromaticity (HOMA) index elucidated the impact of hydrogen bonding in the ring. Intramolecular hydrogen bonding energy has been calculated from topological study. The lowwavenumber vibrational modes obtained from experimental FT-Raman spectrum also supported the presence of hydrogen bonding. Bands are assigned for vibrational frequencies using DFT/B3LYP/6-311++G** level of theory.
