Abstract
We examined photochemical degradation of energetic molecules upon UV resonance Raman (UVRR) excitation of the 229 nm UVRR spectra of solid HMX, TNT and RDX. Comparisons of the UVRR spectra of these photodegraded samples to those of different carbon samples indicate some features similar to carbon compounds with sp2 bonding, vaguely reminiscent of graphitic carbon as well as amorphous carbon. Spinning the energetic material samples minimizes the per molecule photon flux which decreases the photochemistry. We very roughly estimated photochemical degradation quantum yields of <10-6.
