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.
