Abstract: Quantum chemical calculations of molecular geometry, HOMO-LUMO, Mulliken charge distributions and vibrational assignments of 4-methoxyaniline hydroquinone (4MAHQ) were carried out by DFT (B3LYP) and HF methods. Spectral analysis on 4MAHQ has been studied both by the computational and experimental methods to assign vibrational modes of all the functional groups. The investigation is extensive to calculate the FMOs, population analysis, Molecular Electrostatic Potential and Non Linear Optical efficiency of 4MAHQ. The electron affinity, ionization and chemical potential, electrophilicity index, chemical hardness, electro negativity and global softness of 4-methoxyaniline hydroquinone were calculated by FMO analysis.
Keywords: Density Functional Theory, HOMO-LUMO, FTIR/FT-Raman, NLO.
