Abstract : By operating the ion source of a mass spectrometer at pressures above 0.2 Torr, equilibrium constants have been obtained for the proton transfer reaction of methanol with benzene, and of both methane thiol and dimethyl ether with toluene and the three xylenes. The resulting free energies when combined with the known proton affinities of the reference compounds (and assuming zero entropy of reaction) gives the values for the proton affinities. (Author)
