8. The SBH+ theory is the one generally accepted., especially on grounds of resonance Raman studies: Callender., R.; Honig., B. Annu. Rev. Biophys. Bioeng. 1977., 6., 33. However., there is some controversy regarding the SBH+ theory. For leading references see: Favrot., J.; Leclercq., J. M.; Roberge., R.; Sandorfy., C.; Vocelle., D. Photochem.
