N2 - The gas phase over the ionic liquid 1-methylimidazolium ethanoate, [Hmim][O2CCH3], was studied by means of Raman spectroscopy. Raman spectra are presented, the species in the gas phase are identified, and their bands are assigned. The results are interpreted using ab initio quantum mechanical calculations that also predict vibrational spectra. The obtained data reinforce a previous interpretation, based on FT-ICR mass
spectrometric data, that the vapor phase over [Hmim][O2CCH3] consists predominantly of two neutral
molecules, monomeric ethanoic acid and 1-methylimidazole.
