Understanding fundamental photo-induced proton-coupled electron transfer (PCET) reactions of small molecules is central to research ranging from solar fuels, biological signalling, and organic electronics. By combining spectral and kinetic information of the photo-generated excited states and radical species present, researchers are able to elucidate the PCET reaction mechanisms involved in these applications. The Edinburgh Instruments LP Transient Absorption Spectrometer is the world’s only commercial system capable of recording instantaneous spectral information utilising an ICCD camera, while then easily being able to switch to measuring kinetic data on a PMT detector – all under software control. It was used to carry out the research in this application note.
