Vapor-Phase Infrared Absorptivity Coefficient of O,S-Diethyl Methylphosphonothioate

Abstract

We measured the vapor-phase absorptivity coefficient of O,S-diethyl methylphosphonothioate in the mid-infrared (4000-550 cm') at a spectral resolution of 0.125 cm(-1). The material used in the feedstock was synthesized at the U.S. Army Edgewood Chemical Biological Center, and the purity was verified by gas chromatography and nuclear magnetic spectroscopy. We describe the experimental method used to acquire the individual spectra that were used to produce the composite spectrum and summarize the statistical uncertainties in the data.
