Reaction Chemistry in IMR-MS

The three atomic reagent ions in IMR-MS (V F variety) react with an analyte by electron transfer and dissociative electron transfer. 

Reactions (8.13-8.15) have a combined rate coefficient of k=8.5 x 10 ° cm s and the reaction branching ratios are given in parenthesis. The advantage of the mercury ion is that it does not react with the ambient air matrix for samples in air. 

Here a fast electron transfer reaction occurs between Hg and benzene.
