Abstract
A study is made of IR and UV spectra of N-oxides of nitroisoxazolinones, and of derivatives of isoxazolidine and isoxazolizidine. Absorption bands are related to valence vibrations of N-O in the NO2 group; in conjugated systems (in N-oxides of nitroisoxazolines) ν s and γ as are equal to ∼1310 and ∼1510 cm−1, in nonconjugated systems (in nitroisoxazolidines) ∼1360 and ∼1560 cm−1, respectively. Frequencies of N-O bond vibrations in N-oxides appear in the region 830–870 cm−1, of the O-N-O fragment in isoxazolidines and isoxazolizidines in the 1010–1060 cm−1 region. Measurements are made of total intensities of N-O valence vibrations in the NO2 group in N-oxides of nitroisoxazolines and nitroisoxazolizidines, as well as of C=N valence vibrations in N-oxides of nitroisoxazolines.
