The Molecular Structure of Morpholine and the Morpholine-H2O Complex Determined by FT Microwave Spectroscopy.
The rotational spectrum of the morpholine-H2O complex was measured and assigned using a Balle-Flygare type FT microwave spectrometer. Rotational, quartic centrifugal distortion, and 14N quadrupole coupling constants were determined, and a N ellipsis H-O hydrogen-bonded structure was found to be consistent with the derived molecular parameters. Additionally, the rotational spectrum of the 13C and 15N isotopomers of the morpholine monomer were measured in natural abundance to determine its r0 structure and a partial heavy atom rs structure.
