Summary on Grant Application Form |
The proposed research programme aims to use mass-resolved threshold ionisation techniques to study ion-molecule reactions occurring within ionic clusters. Cluster ions play an important role in many chemical processes and are abundant in many gas phase environments. Furthermore, many cluster ions have been proposed as analogous to collision intermediates in gas phase bimolecular reactions. The study of reactions occurring within clusters provides an opportunity to forge a link between the fields of bimolecular gas phase reaction dynamics and solution chemistry. The programme will use nanosecond pulsed dye lasers to prepare a series of different cluster cations (see above) in energetically well defined vibronic states and subsequent intracluster ion-molecule reactions will be followed by measuring product ion branching ratios as a function of internal energy. Progressive changes in behaviour with cluster size will provide insight into the effects of solvation on the reaction and lead to a better understanding of how reaction dynamics change with changes in phase. Furthermore, the spectroscopy of the parent ion will provide a valuable source of thermodynamic data such as ionisation energies and binding energies.
