Intermolecular proton transfer in anionic complexes of uracil with alcohols
Article Abstract:
A series of 18 alcohols (ROH) is designed with an enthalpy of deprotonation in the gas phase in the range 13.8-16.3 eV. For ROHs with deprotonation enthalpies smaller than 14.3 eV, the excess electron attachment to the ROH...U- complex always induces a barrier-free proton transfer from the hydroxyl group of ROH to the O8 atom of U, with the product being RO-...HU.

Excess electron attachment induces barrier-free proton transfer in atomic complexes of thymine and uracil with formic acid
Article Abstract:
The anionic complexes of formic acid with uracil and thymine reveal broad photoelectron spectroscopy features centered at 1.7 and 1.11 eV, respectively. The difference in experimental spectra of UF- and TF- provides an indication that the methyl group of thymine could make a difference in the intermolecular proton transfer.

Excess electron attachment induces barrier-free proton transfer in binary complexes of uracil with H2Se and H2S but not with H2O
Article Abstract:
The photoelectron spectrum of the anionic uracil-H2S anionic complex (UH2S)(super -) is recorded with 2.540 eV photons. The (UH2S)(super -) spectrum reveals a broad feature with its maximum between 1.7 and 2.1 eV.
