Abstract : The gas phase basicity and proton affinity of a molecule, M, are both defined in terms of the hypothetical reaction: M + H(+) yields MH(+). The gas phase basicity is the negative of the corresponding enthalpy change. The available data on gas phase basicities and proton affinities of molecules are compiled and evaluated. Tables giving the molecules ordered (1) according to proton affinity and (2) according to empirical formula, sorted alphabetically are provided. The heats of formation of the molecules and the corresponding protonated species are also listed. Originator supplied keywords include: Basicity; Heats of formation; Ion-molecule reaction; Proton affinity; and Proton transfer.
