Structural, vibrational, magnetic and electronic properties of N-phenylpropanamide were analyzed experimentally and theoretically. The molecular geometry optimization parameters, vibrational wavenumbers, proton and carbon NMR chemical shifts, frontier molecular orbitals and UV-Vis. wavelengths were computed with DFT/B3LYP method at the 6-311+G(d,p) basis set to compare the experimental data obtained from the literature. Calculated harmonic vibrational wavenumber assignments were obtained from the potential energy distribution (PED) analysis. Considering that the N-H…O intermolecular hydrogen bond interaction in crystal packing of N-phenylpropanamide may exist, molecular structure parameters and vibration frequencies of these groups in this interaction were investigated. UV-Vis. electronic absorption parameters, HOMO-LUMO analyses and molecular electrostatic potential (MEP) surface of N-phenylpropanamide were studied to explicate electronic transitions, intramolecular charge transfer and interaction sites in the molecule.
