Time-Resolved Infrared Spectroelectrochemistry

Abstract

The generation of time-resolved infrared spectra of species formed at the electrode-solution interface is reported. The methodology involves electronic pre- or post-coupling of the electrochemical experiment to the interferometer retardation timing. By the sorting of the data points in each of the resulting sets of interferograms, which are accumulated over finite intervals of time after initiation of the electrochemical experiment, spectra representing very short integrated time periods are obtained. These time discretized spectra represent the time evolution of the vibrational structure at the electrode surface.
