Abstract Details

2013, Doctor of Philosophy, Miami University, Chemistry and Biochemistry.
The goal of the research performed for this thesis was to further develop and evaluate vibrational spectroscopic techniques, specifically infrared and Raman spectroscopies, in challenging sampling situations. Some experiments focused on analyzing samples with techniques that had limited to no previous research while others focused on modifying current techniques providing alternate and possibly improved methods of detection and analysis. Chapter 1 provides background into the fundamentals of infrared and Raman spectroscopy and briefly covers sampling techniques available. Chapter 2 demonstrates that a commercial Raman microscope can be externally modified to sample using attenuated total internal reflectance (ATR). This modification allowed the collection of nanometer thin films without spectral contamination from sub-layers and demonstrated improved collection parameters. Chapter 3 evaluated a constructed dispersive Raman spectrometer operating with near–infrared (NIR) wavelengths to determine polyethylene terephthalate film thickness for process monitoring purposes. Chapter 4 demonstrated the potential capabilities of NIR-diffuse reflectance spectroscopy for the detection of high energy materials to provide alternative methods of detection and increase safety in the battlefield. Chapter 5 was an investigation of a planar array spectrograph employed as a real-time detector for liquid chromatography separations.
