Infrared multiple photon dissociation spectroscopy of protonated histidine and 4-phenyl imidazole
TL;DR: In this article, the gas-phase structures of protonated histidine and the side-chain model, Protonated 4-phenyl imidazole (PhIm), were examined by infrared multiple photon dissociation (IRMPD) action spectroscopy utilizing light generated by the free electron laser FELIX.
Journal ArticleDOI
Communication: Theoretical exploration of Au++H2, D2, and HD reactive collisions
TL;DR: A new global potential energy surface has been developed based on multi-reference configuration interaction ab initio calculations, and it is found that the total dissociation into three fragments, Au(+)+H+H, is the dominant reaction channel for energies above the H(2) dissociation energy.
Journal ArticleDOI
Reactions of Ar+, Ne+, and He+ with SiF4 from thermal energy to 50 eV c.m.
M. E. Weber,P. B. Armentrout +1 more
TL;DR: In this paper, the cross sections for reaction of SiF4 with Ar+, Ne+, and He+ from thermal to 50 eV were measured using guided ion-beam techniques, where charge transfer followed by loss of F atoms are the sole processes observed.

Ligand Exchange Reactions of Sodium Cation Complexes Examined Using Guided Ion Beam Mass Spectrometry: Relative and Absolute Dissociation Free Energies and Entropies
TL;DR: In this paper, guided ion beam mass spectrometry is used to study the ligand exchange reactions of Na+L1 with L2, where L1, L2 = H2O, C6H6, CH3OCH3, NH3, and C2H5OH, as a function of kinetic energy.
