Reaction Kinetics group -- Dr. Arkke Eskola

Welcome to the Reaction Kinetics group! Our research interests focus on reaction kinetics and oxidation chemistry in the gas phase, both under normal atmospheric conditions and during low-temperature combustion (auto-ignition).

We have developed our own experimental tools:

  • Laser Photolysis -- Photoionization Mass Spectrometer (LP-PIMS)
  • Time-Resolved Broad-Band Cavity-Enhanced Absorption Spectrometer (TR-BB-CEAS)
  • + more systems under construction

We also do theoretical/computational studies using kinetic models to complement our experimental work.

More information can be found at our website.
