Understanding the Light-Harvesting Photosystem II; Utilising Transient Absorption to Study a Molecular Triad’s Photoinduced Electron Transfer Reactions

The ability of plants to live, thrive and survive on sunlight provides unsurpassed motivation to understand and mimic this process for solar energy production. In this application note, Edinburgh Instrument's LP980 Transient Absorption Spectrometer is used to measure energy and electron transfer events.

Kinetics of Photocatalysis Reactions Studied by Transient Absorption Spectroscopy

Photocatalysis is the rate increase of a chemical reaction by light, often in the presence of a catalyst that starts the reaction upon irradiation. Photocatalysts are typically semiconducting metal oxides such as ZnO, Fe2O3 or TiO2 which are employed as particles in solution. When absorbing light, these materials are able to generate electrons and holes which go on to react with chemical species on their surface. Find out how our LP980 Spectrometer was used in this recent application note.

Proton-Coupled Electron Transfer (PCET); Spectral and Kinetic Transient Absorption Analysis of Acridine Orange with Tri-Tert-Butylphenol

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.
