Luminescence Properties of RDX and HMX

Abstract

Optical absorption measurements have confirmed the reports of earlier workers that the solid forms of the cyclic polynitramines known as RDX and HMX have a weak absorption band in the near ultraviolet which is not observed in spectra of the solvated compounds. Fluorescence measurements on solid samples of these materials show a weak emission, the excitation spectrum of which corresponds to this absorption band. The fluorescence is also not observed in the solvated compounds. Phosphorescence measurements on the solids reveal a long-lived emission, the excitation spectrum again corresponding to the band observed in absorption and fluorescence excitation. The lifetime of this emission was found to be substantially increased by deuteration. The absorption and luminescence bands are attributed to charge-transfer self-complexation in the solid state, and estimates of the charge-transfer singlet and triplet excited state energies are given.
