Chemical processes occurring in shock-compressed and detonating high explosives have been studied using fast time-resolved emission spectroscopy and a two-stage gas-gun. The spectral characteristics of emission from shock-compressed nitromethane, tetranitromethane and single crystals of pentaerythritol tetranitrate are typically very broad and structureless, likely representing thermal emission. Assuming the thermal emission from a gray-body, the emission intensity can be correlated to the temperature changes in shock-compressed and detonating high explosives. We report Chapman-Jouguet temperatures of 3800 K for nitromethane, 2950 K for tetranitromethane, and 4100 K for pentaerythritol tetranitrate. In this paper we also compare the data with the chemical equilibrium models. {copyright} {ital 1996 American Institute of Physics.}
