The FT-IR and FT-Raman spectra of N-(3-iodo-4-methylphenyl)pyrazine-2-carboxamide were recorded and the experimentally observed wavenumbers are compared with the theoretically obtained wavenumbers. The redshift of the NH stretching mode in the IR spectrum from the computed value indicated the weakening of the NH bond. The ring breathing modes of the phenyl ring and pyrazine ring are assigned at 819...
