Theoretical study of the H 3 + ion dissociative recombination process
We report recent developments in the theory of dissociative recombination of the H3 ion. The theory is able to explain the surprisingly large dissociative recombination rate observed in storage-ring experiments. We have found that the high rate is caused by Jahn-Teller coupling between the electronic and vibrational degrees of freedom. We compare two theoretical models: A simplified model and a...
متن کاملDissociative recombination angular distributions
The angular distributions of the products of dissociative recombination of diatomic molecular ions are derived. The distributions are determined by the dominant partial waves of the captured electrons. For a single dominant wave, the neutral product distribution is described by the same spherical harmonic that describes the electron partial wave. The derived distributions take into account both...

متن کاملDissociative recombination of protonated methanol.
The branching ratios of the different reaction pathways and the overall rate coefficients of the dissociative recombination reactions of CH3OH2+ and CD3OD2+ have been measured at the CRYRING storage ring located in Stockholm, Sweden. Analysis of the data yielded the result that formation of methanol or deuterated methanol accounted for only 3 and 6% of the total rate in CH3OH2+ and CD3OD2+, res...
متن کاملFragmentation of doubly-protonated peptide ion populations labeled by H/D exchange with CD(3)OD.
Doubly-protonated bradykinin (RPPGFSPFR) and an angiotensin III analogue (RVYIFPF) were subjected to hydrogen/deuterium (H/D) exchange with CD(3)OD in a Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometer. A bimodal distribution of deuterium incorporation was present for bradykinin after H/D exchange for 90 s at a CD(3)OD pressure of 4 x 10(-7) Torr, indicating the existence of...
