Research in our lab involves development of FT-MS and IR spectroscopic techniques and their application to problems in physical geochemistry and ore fluid processes in particular. Our interests currently include the use of IR lasers for multiphoton dissociation (IRMPD) measurements of solvated ion clusters. The experimental set-up includes a modified Bruker FT-MS facility and Nd:YAG pumped OPO/OPA laser system that delivers tunable infrared radiation in the mid IR range. This set up is used to carry out FT-MS and IRMPD experiments on small ion clusters and related materials with a focus on the structure of ion core and the configuration of the solvation shell surrounding the solute. We also complement our experiments with DFT and ab initio calculations to better understand the structures and properties of these molecular clusters.
