| Spectroscopic studies using absorption spectroscopy (AS), photofragmentation spectroscopy (PF-LIF), and cavity ringdown spectroscopy (CRDS) were preformed on 2,4,6-Trinitrotoluene. The NO detection of the energetic material (EM) was done using combinations of the previous procedures. Calculations for the absorption coefficient and cross sections were obtained. The procedure of photofragmentation required heating of the sample to generate an absorption curve and a cross section. Absorption spectroscopy, which covered a range of 195-300 nm, also corresponded with the use of heating the sample to obtain the two values. Cavity ringdown spectroscopy investigations were done on the sample at room temperature. A higher accuracy for the level of detection was obtained using a combination of photofragmentation at various wavelengths and cavity ringdown spectroscopies. |
