ABSTRACT
Since organophosphorus nerve agents are among the most toxic known chemical warfare agents, it is desirable to have a way to distinguish between one and another. Infrared spectroscopy is a common tool for identifying molecules. Given the difficulty in handling these chemicals, calculated IR spectra can be useful. Calculated IR spectra are presented for G agents, V agents, and simulants. Quantum chemistry calculations were performed using the Gaussian 03 package at the B3LYP/6-31+G(d,p) level of theory. The most prominent IR lines are due to vibrations of P-O-C and P=O groups within the molecules. It should be possible to distinguish between the G-series and V-series agents using IR spectroscopy, but unique identification of individual chemical agents is unlikely.
