Abstract: The objective of this experiment was to determine if soil particles could be matched to a known soil sample by infrared microspectroscopy. The infrared spectrum for soil samples collected at five different locations was collected. These samples were labeled as followed: Creek Side Golf (CSG), Mossy Oak Woods (MOW), Mossy Oak Yard (MOY), Sparrow Drive (SD), and Wilmington Beach (WB). These spectrums severed as a standard and were compared to two unknown soil samples randomly selected from the five locations. Based on the spectrum it was determine that unknown 1 came from the Sparrow Drive and unknown 2 came from Mossy Oak Woods. This proves that it is possible to determine the origin of trace soil particle. In order to determine if this holds true in all instances, a larger sample size and unknowns would need to be examined The practical application for this experiment would be matching trace soil evidence found on a victim or suspect to a specific crime scene.
