The IR spectra of several compounds containing the nitro group were studied. Based on these and previous data, the state of the nitro group depending on the structure of the fragments bound to the nitrophenyl group was discussed. The redistribution of the electron density at vibrations of the nitro group and the substituent atoms was considered. The effects of the ,-t-bond system, bridging atoms separating the nitrophenyl group from the substituents, and heavy atoms adjacent to the bridging atom were characterized. The data obtained facilitates the orientation in the selection of molecular structures satisfying the specified requirements of practical applications.
