Flash pyrolysis of energetic compounds that are unusually rich in nitrogen can be expected to liberate a large amount of N2 among other products. In addition H2 and O2 can
be pyrolysis products from other types of energetic compounds. While many kinetics and mechanistic details have been learned from T-jump/FT-IR (Fourier transform infrared) spectroscopy, the development
of the complementary method of T-jump/Raman spectroscopy described herein helps to complete the elemental atom balance of the gaseous products. Differential Raman scattering cross sections were determined
for many of the common gases resulting from pyrolysis of energetic compounds. The spontaneous Raman scattering by the products of hydrazinium [3-nitro-4-nitraminofurazan], poly(bis(3,3'-azidomethyl)oxetane),
poly(glycidyl azide) as the mono-ol derivative, and 5-nitriminotetrazole were determined. Provided that at least one of the quantified species is common to both the IR and Raman spectra, the Raman-based
data can be combined with the IR data to give a properly balanced gasification reaction.
