Fourier-transform resonance Raman spectra of cation carotenoid in photosystem II reaction centres.
Resonance Raman spectra of the cation form of a redox-active carotenoid in photosystem II are presented. These results have implications for the nature of the carotenoid radical and in particular the localisation of the hole on this molecule.
