Abstract

Abstract Analysis of the vibration and rotation spectra together with NMR and mass spectral data for E-propene-1-thiol has shown that the molecule exists in the gas phase in a conformation with the thiol hydrogen atom in a non-planar, near anti orientation with respect to the double bond. This result is assessed in the light of ab initio predictions indicating the existence of both a syn and gauche rotameric form for the molecule.
