Chemical and physical reactions on or with surfaces are an important part of chemistry, underpinning a big part of heterogeneous catalysis and electrochemistry. The measurement of small amounts of material on surfaces can be challenging, especially on short timescales.

This webinar, presented with Prof. Ian Burgess from the University of Saskatchewan, explores the application of dual comb spectroscopy (DCS) to fast phenomena on surfaces. Using surface enhanced infrared absorption spectroscopy (SEIRAS) with DCS, the potential-dependent adsorption of dimethylaminopyridine on gold was studied on a microsecond timescale. With the bright laser source of the dual comb spectrometer, the acquisition time was decreased by two orders of magnitude compared to similar FTIR experiments.

The webinar was held on 28 May 2020.
