N2 - The radical cations of chlorophyll a (Chl a) and bis ( chlorophyll )cyclophane (BCP), a synthetic model dimer of chlorophyll, were studied by ENDOR and TRIPLE resonance in liquid solution. The measured hyperiine coupling constants (hfcs) of Chl a+ were compared with the results of molecular orbital calculations. By comparing the hfcs of BCP+ and Chl a+ a localization of the unpaired electron on one macrocycle of BCP+ is deduced.
