Abstract
Correlations have been established between the values of the frequencies and intensities of the bands due to the two stretching vibrations of the nitro group and the structure of molecules. The use of band intensities extends considerably the possibilities in structural analysis, and makes it possible to distinguish reliably saturated, unsaturated, and aromatic nitro compounds and to make a more detailed differentiation between compounds within classes. It has been shown that the intensities are additive and that the intensity of one of the vibrations is highly characteristic; quantitative determination of nitro groups in molecules of unknown structure is possible.
