Structure and Chemical Reactivity of Size-Selected Clusters in Gas Phase (A01)

• Subject Area: Physical Chemistry of Molecules, Liquids and Interfaces, Biophysical Chemistry
• Term: since 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 426888090

The project aims to elucidate structure-reactivity relationships, reaction and deactivation mechanisms, and the role of different size regimes in the oxidation of NH3 and CH4 on ionic Ptn, Pdn and Run (n<100) clusters in gas phase. A unique combination of a structure sensitive method (TIED) and reactivity measurements (RITMS) under different reaction temperatures and reactant pressures will allow to unravel the origins of reactivity on an atomic scale. In this way, intrinsic cluster properties can be identified, analyzed by ab initio computations, and the reactivities compared to those of realistic systems.
