•B3LYP as well as FTIR were utilized to analyze Perylene-66.•Vibrational assignments for Perylene-66 were aided at B3LYP/6-311G(d,p).•Perylene-66 has a high dipole moment (3.6 Debye) and HOMO/LUMO energy gap (3.2 eV).•Perylene-66 is a promising structure for optoelectronic devices as solar cells.
In the present work, a combined experimental and theoretical study on molecular structure and vibrational frequencies of Perylene-66 were reported. The FT-IR spectrum of Perylene-66 is recorded in the solid phase. The equilibrium geometries, harmonic vibrational frequencies, thermo-chemical parameters, total dipole moment and HOMO–LUMO energies are calculated by DFT/B3LYP utilizing 6-311G(d,p) basis set. Results showed that Perylene-66 is highly recommended to be a promising structure for many applications in optoelectronic devices due to its high calculated dipole moment value (3.6 Debye) and lower HOMO–LUMO energy gap of 3.2 eV.
