摘要：

Samples of long-term aged TD-50 and tetryl were investigated by UV-VIS and FTIR spectroscopy and bands of products of ageing were obtained. A complicated maximum of nitro groups at 1537 cm(-1) in the FTIR spectra of long-term aged explosives was obtained, like in the IR spectra of long-term aged single-based propellants. Ageing process was confirmed by the presence of several maxima in UV-VIS and FTIR spectra of aged products and determination of several characteristics of the investigated explosives (shifts Delta v, differences in absorbances Delta A, differences in values of Delta h*(1/2)). Ageing was connected with decrease of H-bond formation on the base of decrease of content of oxygen and nitro groups in TD-50 and tetryl.
