Wayne State University Dissertations
This dissertation is focused on the development of a new experimental apparatus that combines two powerful techniques: Chirped-Pulse Fourier-Transform Microwave (CP-FTMW) spectroscopy and uniform supersonic flows. This combination promises a nearly universal detection method that can deliver quantitative isomer, conformer, and vibrational level specific detection; characterize unstable reaction products and intermediates; and perform unique spectroscopic, kinetics and dynamics measurements.
Thus, a new high-power Ka band (26 – 40 GHz) chirped pulse spectrometer with sub-MHz resolution was designed and constructed. In order to study smaller molecules, E-band (60 – 90 GHz) capabilities were also added to the spectrometer. A novel strategy …
