Four decades ago, when Lou Duysens was about to start his work on
fluo rescence and energy transfer in photosynthesis that would lead
to his thesis [1], very little was known about the molecular
mechanisms of photosyn thesis, certainly from our present-day point
of view. However, this state of affairs would rapidly change in the
ensuing years by the introduction of modern physical and
biochemical techniques. Especially the field of optical
spectroscopy, on which the work of Duysens had such a significant
impact, has proved to be one of the most fruitful techniques in the
study of primary processes and electron transfer reactions in
photosynthesis. Duysens' thesis established the role of energy
transfer in photosynthesis and also showed for the first time the
existence in photosynthetic bacteria of light-induced absorbance
changes of what is now known as the primary electron donor P-870.
Subsequent studies by the same method demonstrated the
photo-oxidation of cytochromes, both in bacteria [2] and in algae
[3,4] and of the absorbance changes [3] that were later found to be
due to electro chromic band shifts of antenna pigments.
Measurements of cyto chrome kinetics in light of various
wavelengths led to the concept of two photosystems in green plant
photosynthesis [5], whereas a study of the factors affecting the
fluorescence yield of chlorophyll gave the first infor mation on
the electron acceptor Q of photo system II [6].
