Infrared absorption cross sections of several organo-phosphorous chemical-weapon simulants
Abstract
Due to extreme toxicity of chemical warfare agents, experiments to study their combustion behavior are commonly carried out using Organo Phosphorous Compounds (OPCs) as simulants. In this study, gas phase absorption cross sections of five common OPC simulants - TMP, DMMP, TEP, DEMP and DIMP have been measured within 650-3500 cm-1 wavenumber range (2.85-13.33 μm) at 295 K and 1 atm pressure (broadening gas: N2). The quantitative absorption spectra reported in this study will be useful in setting up laser based diagnostics schemes to study their chemical kinetics in a shock tube.
