Ro-vibrational distribution measurement in transient discharges by precision frequency comb spectroscopy (A02)

• Subject Area: Optics, Quantum Optics and Physics of Atoms, Molecules and Plasmas
• Term: since 2018
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 327886311

The energy distributions of molecules generated by the plasma provide insight into the generation of reactive species and reaction mechanisms relevant for efficient conversion. This project utilizes frequency comb spectroscopy, which uniquely provides broadband coverage, high resolution and sensitivity, to determine partition functions for CO and CO2. These partition functions are also used to validate numerical simulations.
