Abstract

The rotational spectra of 2,2-dimethyloxirane and 2-chloroethanol from 8 to 26 GHz were obtained using a waveguide, chirped-pulse microwave spectrometer at room temperature, and the rotational spectrum of 2-vinyloxirane from 75 to 110 GHz was obtained by collaborators at BrightSpec using a BrightSpec Fourier Transform- Molecular Rotational Resonance (FT-MRR) Broadband Discovery Spectrometer. Each spectrum was examined to refine rotational and distortion constants for the ground state of the dominant conformer for each molecule. For 2-chloroethanol, the ground state of the dominant conformer for both isotopologues was examined. For all three molecules, additional transitions were assigned within the spectrum, improving upon previous work. Ab initio calculations have been performed for future use in the assignment of additional excited states and conformers.
