Abstract
Room-temperature rotational spectra are dense and difficult to assign. In this thesis, two different methods were developed with a waveguide-based spectrometer that operates from 8.7 to 26.5 GHz. The first method, based on previous work by Medvedev and De Lucia, was used to estimate lower state energies of transitions by performing relative intensity measurements at a range of temperatures between -20 and +50C. The second method employed microwave-microwave double resonance measurements to determine level connectivity between rotational transitions. The relative intensity measurements were not particularly successful in this frequency, but the information gleaned from the double resonance measurements can be incorporated into other spectral search algorithms via penalty functions to simplify the spectral assignment process.
