The UV Absorption Spectra of Chemical Agents and Simulants

Volume 40, Number 2 (Feb. 1986) Page 152-156

Rewick, Robert T.; Schumacher, Mary L.; Haynes, Daniel L.


The uv spectra of chemical agents GA, GB, GD, VX, HD, and L and common agent simulants have been measured in cyclohexane solution from 350 to 200 nm. The purity of the agents, measured by gas chromatographic analysis, was in general >96%. At 230 nm, the strength of the uv absorption followed the general trend L > VX > GA > HD > GD > GB > DMMP. Except for HD and L, agent spectra lacked characteristic features that will be useful for remote detection by uv sensors.
