This work deals with a theoretical study of the molecular structure of 3-(2-Nitrophenoxy) phthalonitrile. The equilibrium geometry, harmonic vibrational frequencies, infrared intensities in scattering activities was calculated by the ab initio Hartree-Fock method and the Density Functional B3LYP method employing 6-311g (d, p) as the basis set. A detailed interpretation of the infrared spectra of 3-(2-Nitrophenoxy) phthalonitrile is reported. The scaled theoretical wave numbers are in perfect agreement with the experimental values.
