Our last work on a new species that undergoes coupled intramolecular proton- and electron-transfer processes has been published in the web page of Photochemical and Photobiological Sciences. The species described presents a structure that may be relevant to the design of new UV photoprotectors. In addition, we describe a method for solving strongly overlapping spectra.
