Abstract Details

2015, Doctor of Philosophy, Miami University, Chemistry and Biochemistry.
This dissertation describes five unique projects which advance spectroscopy in terms of education, technology and applications. Project goals were designed so the end results would assist with solving educational, military and industrial challenges through the use of spectroscopy. These goals were accomplished through the use of new, existing and adaptations of existing spectroscopic instrumentation. New spectroscopic instruments were developed and built for use in educational teaching laboratories at Miami University. These instruments included a low-cost Raman spectrograph and a low-cost flame atomic emission spectrometer. Both instruments have economic and educational benefits over commercial instruments and the flame emission instrument has already demonstrated its value in the classroom. The next project, driven by military interest, involved using near-infrared diffuse reflectance spectroscopy for the standoff detection of explosive materials on common surfaces. Projects included coating substrates with high energy materials and acquiring spectra from those coated substrates. Results showed differences in the detection limits for ammonium nitrate on various substrates, and these limits were directly dependent on the characteristics of the substrate. Another project was completed in collaboration with the United States Food and Drug Administration’s Forensic Chemistry Center. This project’s goal was to identify counterfeit goods based on their packaging materials. By taking a cross section of a packaging material and acquiring a high resolution attenuated total internal reflection (ATR) Fourier transform infrared (FTIR) image, differences could be revealed which showed variances between the authentic and counterfeit packaging materials. Finally, an adaptation of an ATR-FTIR microscope was used in an attempt to improve the spatial resolution of an ATR-FTIR image by working in a non-contact type sampling configuration. Improvements in spatial resolution have not yet been demonstrated.
