Quantitative UV Absorbance Spectra of Chemical Agents and Simulants

摘要

The quantitative UV absorption spectra of selected chemical agents and simulants have been measured for wavelengths in the near UV from 200 to 400 nm. Although these data are of interest in their own right, they are also necessary for predicting the sensitivity of UV Raman based detection systems. Of particular interest are the absorption values at 248.25 nm and 262 nm as these correspond to excitation wavelengths used by UV Raman based surface contamination detectors currently under development. These wavelengths are produced by KrF excimer lasers and quadrupled Nd:YLF lasers, respectively. This report collates these data in a presentable form.
