Abstract: IDuring the past year we have obtained a large amount of data on chlorophyll-qu inone photoreactions in alcohol solvents using flash photolysis, steady-stat e absorbance changes and ESR.This is now being written up in four manuscripts.Unfortunately, these are not in final enough form to append to this report.In lieu of this, I will include here a summary of the conclusions we have drawn concerning reaction mechanisms, without trying to present the supporting data.The simplest reaction of chlorophyll triplet with an alcoholic solvent would be hydrogen abstraction (inasmuch as a similar photoproduct is obtained in tert.-butanol, the hydroxyl hydrogen would seem to be involved): k Chl + hv + Chls + ChlT +1 Chl ............. (1) k2 Chl + ROH + ChlH• + RO• ............. (2) T (kl represents all modes of decay of the triplet state)
