Title: A CONTRIBUTION TO THE UNDERSTANDING OF THE PRIMARY QUANTUM CONVERSION IN PHOTOSYNTHESIS

Technical Report ·
OSTI ID:4020776

A general consideration of the efficiency requirements foi the quantum conversion process in photosynthesis is made. This leads to the concept that a most likely primary quantum conversion process would be an electron transfer process following molecular excitation Model systems of the various types of known quantum conversion processes are discussed, followed by the presentation of evidence concerning the nature of the primary quantum conversion process in the photosynthetic apparatus of bacteria. That an electron transfer process is very early involved seems unambiguously established. That exciton transfer takes place following pnimary quantum absorption seems also well established. Some supporting evidence is given to show that charge migration in the sense of semiconductor behavior also occurs. (auth)
