Recently there has been an increase in the use of peroxide-based explosives to their low cost and ease of synthesis. Because of this, researchers are developing techniques with the single purpose of detecting these types of explosives. One type in particular is Spatially Offset Raman Spectroscopy (SORS). In the process of developing this technique it was observed that as the concentration of peroxide increased in a given sample there was a corresponding change in the observed oxygen-oxygen Raman shift. Explanation of this phenomenon is unknown at this time. This research focused on answering this question by using Raman spectroscopy along with the Gaussian 09 software package.
