The use of the nitrolysis of cyclic amines and of the direct synthesis from primary nitroamines made it possible to obtain acetates of methylolnitroamines of general formula AcO(CH2NNO2)n R(n = 1–6). A number of high explosives, nitroamines, were s

Vibrational spectra of several nitramines in the long-wave region (50–450 cm−1) were studied. The frequencies of intra- and intermolecular vibrations were separated and a tentative assignment of the frequencies of self-associative complexes was p
