Abstract Relative protonaffinities are usually measured by means of high pressure mass spectrometry. In this work ion mobility spectrometry was used to determine protonaffinities. The standard molar enthalpy change ΔH0M for the reaction MH++N⇌M+NH+ was found to be: −(56.3±0.8) kJ · mol −1 , when M was ethyl acetate and N ethanol; −(27.8±0.5) kJ · mol −1 , when M was acetophenone and N ethyl acetate;

Alkyl cation transfer reactions between ethanol and protonated ethanol and ethanol and protonated propionitrile, as well as between n-propanol and protonated n-propanol have been investigated experimentally by low-pressure Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometry. The two ethyl cation transfer reactions were found to be the dominant reaction channels with association being

shown to be much more energy selective than CID. Photodissociation of C(2)H(5)OH(2)(+) ion produces the lowest energyproduct ion exclusively, even though the two product channels differ only by approximately 5 kcal/mol. Low-energy CID, however, produces a mixture of C(2)H(5)(+) and H(3)O(+) products in the ratio of 1.3:1. Hence, the higher energy pathway (C(2)H(5)(+)) is substantially favored. The current
