Photosynthetic antenna proteins: 100 ps before photochemistry starts.
All photosynthetic organisms require a light harvesting system to funnel excitation energy towards the photosynthetic reaction centre, a process which can take 100 ps. Laser spectroscopy allows us to measure rates of energy transfer between pigments of the light harvesting system for the first time. These rates are correlated with models of the light harvesting apparatus.
