  • Complete speciation and thermodynamic analysis of [PtCl6-nBrn]2- (n=0-6)

Research Summary

The main focus of the Gerber group is the elucidation of inorganic reaction mechanisms that range from ligand exchange, redox processes and catalysis cycles amongst others. To this end we continuously develop software for modelling macroscopic reaction kinetics and associated equilibria coupled with the use of existing quantum computational chemistry packages to understand the results at the molecular level. As high quality analytical data is required for thermodynamic and kinetic modeling we actively develop new or improve on existing analytical techniques (NMR, hyphenated separation techniques) specifically for the platinum group metals (PGM’s) present in aqueous or organic solvents.
