Paper Abstract

The polarization modulation infrared reflection absorption spectroscopy (PMIRRAS) spectra of the nerve agents GB (O-isopropyl methylphosphonofluoridate) and GF (cyclohexyl methylphoshonofluoridate) were recorded for the first time. A comparison of these spectra with the nerve agent VX (ethyl S-2-diisopropylaminoethyl methylphosphonothiolate) and the spectra of some trialkyl phosphates indicates that it is easy to distinguish between chemical warfare agents and simulants on militarily-relevant surfaces using PMIRRAS.
