•FT-IR and FT-Raman techniques combined with DFT calculations have been utilized to obtain a complete vibrational analysis of the title compound.•NBO, MESP and Mulliken analysis were studied.•The calculated HOMO LUMO energies show that charge transfer occurs within the molecule.•Molecular docking verifies the herbicidal activity of the title compound. The FT-IR and FT-Raman spectra of Bifenox, Methyl 5-(2, 4-Dichlorophenoxy)-2-Nitrobenzoate have been recorded in the range 4000-450 cm−1 and 4000-50 cm−1, respectively. The optimized molecular geometry calculated using density functional theory with B3LYP method was compared with available experimental data. The distributions of the vibrational bands are carried out with the help of Normal Coordinate Analysis (NCA) and are assigned with the help of potential energy distribution method. Stability of the molecule arising from hyperconjugative interactions and charge delocalization are analyzed using Natural Bond Orbital (NBO) analysis. Molecular Electrostatic Potential (MESP) and HOMO-LUMO analysis are also performed. Docking simulations are done to identify the herbicidal active site of the title compound.
