Abstract

Abstract The zero‐field ODMR of triplet state of chlorophyll a incorporated in phosphatidylcholine (PC) vesicles (Chi a: PC = 1:100) has been carried out. The zero‐field ODMR frequencies and intersystem crossing rate constants have been measured at various fluorescence wavelengths. The ODMR data suggest that the chlorophyll is present in mono‐ and biligated species. The nature of the ligand and the role of the medium (phospholipid) are also discussed.
