Vapor-Phase Absorptivity Coefficient of Ethyl N,N-Dimethylphosphoramidocyanidate

Abstract

We measured the vapor-phase absorptivity coefficient of the chemical warfare agent ethyl N,N-dimethylphosphoramidocyanidate (GA) in the mid-infrared (4000-550 cm"') at a spectral resolution of 0.125 cm"'. The GA used in the feedstock was purified by fractional distillation and analyzed by nuclear magnetic resonance and gas chromatography/mass spectrometry to verify its purity. We describe the experimental method used to acquire the individual spectra that were used to produce the composite spectrum, summarize the statistical uncertainties in the data, and provide a comparison to similar data from another laboratory.
