Abstract
We have investigated oligomeric nature of chlorophyll a in Langmuir-Blodget t films using scanning tunneling microscope. Our observations revealed that chlorophyll a is a dimer and suggest that a similar dimeric condition of c hlorophyll a may exist in the reaction centers of photosystem II.
