Ion beam studies

The Met+—L bond dissociation energies were measured for some Zn-containing gas phase cations using different methods ". Armentrout reviewed guided ion beam studies of transition metal-ligand thermochemistry and reported the following... 

Further support for the instability of SiH4+" comes from studies of the charge transfer reactions of a variety of small ions with SiFLt11. Although almost resonant charge transfer was achieved in the reaction of SiHt with Xe+ (AIE = 0.08 0.21 eV), no SiH4+ cations were observed in these guided-ion beam studies. 

A source of line broadening which is fairly common in molecular beam studies, and often dominant in ion beam studies is transit time broadening. This arises when the interaction time between the electromagnetic radiation field and the molecule is limited by the time the molecule spends in the radiation field. The transit time t is equal to d/v, where v is the molecular velocity and d is the length of the radiation field. A typical...

As far as the author is aware there have been no reports of F ion beam studies with complex target molecules with the exception of some preliminary work on the F + CH. reaction. 

F ion beam studies using simple atomic or molecular targets are suipnarized. The charge transfer between F and Ne, the reaction F with molecu],ar hydrogen and its stable isotopic...
