Photosynthetic energy transfer – duelling dipoles revises previous understanding [Registered]

Chemists at the Ludwig-Maximilians-Universität (LMU) in Munich have refuted a basic postulate of Förster theory, which describes energy transfers between pigment molecules, such as those that underlie photosynthesis. A revised version of the theory could have an impact on the design of optical computers and improve the efficiency of solar cells. Photosynthesis, whereby light energy is converted into chemical energy, is fundamental to life on Earth. In plants, sunlight is collected by the green pigment chlorophyll. The chlorophyll captures the light energy and relays it, virtually without loss, via several intermediate molecules, to the reaction centers, where it is converted…
