Abstract

The rotational spectra of 2-methoxyethanol, 2-ethoxyethanol, and n-propylamine were recorded from 8.7 – 26.5 GHz using a waveguide, chirped-pulse Fourier transform microwave spectrometer at 253 K using a recently designed flow-through chiller system. These molecules were chosen for study because of recent developments in the field of astrochemistry. An automated spectral fitting program, the triples fitter, assisted in assigning the spectra of both 2-methoxyethanol and 2-ethoxyethanol. The triples fitter was recently developed and some guidelines for its use are discussed. The ground state and four vibrationally excited states were fit in the spectrum of 2-methoxyethanol and the ground state was fit in 2-ethoxyethanol. The spectrum of n-propylamine could not be assigned due to a dense data set containing the spectra of five conformers present in roughly equal abundance.
