VIBRATIONAL SPECTRA OF 3-AMINOPHTHALONITRILE

The IR spectra of 3-aminophthalonitrile (3-AFN) were obtained for solid phase. The experimental spectra were assigned using quantum chemical calculations of different level. Comparison of experimental and calculated spectra shows a significant ambiguity of different quantum chemical methods for predicting vibration spectrum in low-frequency range and peculiarities of 3-AFN molecule structure.
