This monograph deals with the light reaction pathway in photosynthesis.
The photophysico-chemical events are presented in the order of their
occurrence, beginning with the collection of sunlight by antenna
systems, ending with the reduction of CO to carbohydrates. Relationships
between the structural 2 properties and kinetic effects of primary and
secondary events spanning time 12 domains in the range 1O- _ls are
explored. Photosynthesis is examined in terms of a light-induced
redistribution of reaction intermediates common to the biosynthesis and
metabolic degradation of carbohydrates. The experimental procedures and
results reviewed in the book are repre- sentative of developments in
instrumental methods and conceptual formula- tions in this area during
the past decade. In particular, picosecond spectroscopy, time-resolved
and magnetic resonance techniques, along with structural and
photoelectrochemical models of photosynthesis, have provided clues for
the molecular mechanisms of energy migration from the antenna systems to
the reaction centers, and of succeeding stages of photochemical events
leading to the carbon-reduction cycle. The preparation of this monograph
resulted from the efforts of workers in distantly separated
institutions. The writer gratefully acknowledges the responsive
collaboration of the contributing authors and members of the Springer
editorial staff that made possible completion of the manuscript.
