- Abstract
- The rapid development of photo(redox) catalysis within the last decades is remarkable to the extent that the utilization of light-driven processes in organic chemistry has become a credible alternative to current thermal processes. Such advances offer tremendous opportunities of collaborations between scientific realms that can have a drastic impact on the development of the field. In this concept article, a special emphasis is placed on spectroscopic techniques that are used, or could be used, for light-induced transformations and photoredox catalysis applications. These include spectroelectrochemistry, UV-VIS, IR and X-Ray transient absorption spectroscopy, laser pulsed radiolysis (PR), photo-induced chemically induced dynamic nuclear polarization (Photo-CIDNP), photoacoustic spectroscopy, time-resolved Raman spectroscopy (TRRS), time-resolved Electron Paramagnetic Resonance (TREPR) and time-resolved dielectric loss spectroscopy (TRDL). The theoretical background behind each technique is briefly introduced followed by selected relevant examples from the literature.
