Comparative Raman Spectroscopy of Nitromethane-h3, Nitromethane-d3, Nitroethane and Tetranitromethane under High Pressure
Nitromethane has been studied as a model of energetic aliphatic nitro-compound. The initiation of the decomposition mechanism of nitromethane in the vicinity of the temperature and pressure conditions of explosion has been studied under high static pressure by Raman spectroscopy. The vibrational modes v<SUB>a</SUB> (NO<SUB>2</SUB>) and, in a smaller scale, v<SUB>s</SUB> (NO<SUB>2</SUB>) show a specific behavior at the solid (II) -solid (III) 7. 5 GPa transition (at ambient temperature). The comparison of the Raman spectrum of nitromethane-h<SUB>3</SUB> with new Raman spectroscopic results under pressure of nitromethane-d<SUB>3</SUB>, nitroethane and tetranitromethane allows to characterize a physico-chemical behavior of these compounds in relation with their exploding properties.
