Paper Abstract

Vapor phase sensing and detection of TNT-based explosives is extremely challenging due in part to the low vapor pressure of TNT. We believe one effective strategy for optically based sensing of TNT-based explosives involves focusing not on the spectral signature for pure TNT, but rather on a more volatile series of compounds that are present in TNT as impurities. To date we have catalogued and reported a number of rotationally resolved infrared transition frequencies for nitrobenzene, toluene, o-nitrotoluene, and m-nitrotoluene in the 14 micron region. Here we describe the use of an in-house spectral calibration program that while designed for calibration of Pb-salt diode laser spectra, is quite general and could be utilized for many spectroscopic detection and/or analysis applications. Finally, a sensing measurement for a volatile organic impurity related to RDX-based explosives such as C4 is presented and discussed.
