Abstract
Ultraviolet resonance Raman spectroscopy (UVRRS) has been used to examine a variety of different isomers of nitroaromatic molecules. Due to the large cross section enhancements possible, UVRRS has the potential to be a sensitive means for detecting trace quantities of explosives at standoff distances. Since it probes both the electronic and vibrational states of the molecules, it can also be a selective means for differentiating between similar molecules. Resonance Raman spectra will be discussed, along with the different trends that are observed, for the different positional isomers of dinitrobenzene. In addition, spectra for the common explosive 2,4,6-trinitrotoluene will be presented.
