Abstract
Room-temperature rotational spectra are dense and the addition of isotopologues further complicate their spectra. In this thesis, three molecules were used as test cases for techniques to simplify complex spectra. The main goal of this work is to establish a guide or tool box of multi-resonance techniques to use during data collection. First, the adaptation of Strong-Field Coherence Breaking for use in the room-temperature waveguide instrument was explored in the case of allyl chloride. While this was unsuccessful in providing information that could not be gathered from double-resonance experiments, reaching the strong-field limit could prove successful in future attempts. Double-resonance measurements were used to simplify the spectra of 2-chloroethyl methyl ether and 1,2-epoxybutane. The measurements for 2-chloroethyl methyl ether were difficult to decipher due to its hyperfine structure, but double resonance was much more selective when applied to 1,2-epoxybutane. Narrower pulse bandwidths should be used in future work to more selectively modulate individual components in hyperfine-containing spectra.
