Resonant picosecond spectroscopy of the physical stages of photo-synthesis with the aid of tunable lasers
The kinetics of the charge-separation process in molecular complexes of the reaction centers has been investigated for the first time by the methods of resonant picosecond spectroscopy. A picosecond spectrometer is described in which both the excitation of the investigated molecules and the registration of the photo-induced spectral changes were effected with the aid of tunable parametric picosecond lasers with well-controlled temporal and spatial characteristics. The quantum yield of the photoexcitation was measured at various wavelengths. The picosecond kinetics of the process was determined. Some new applications of picosecond spectroscopy are discussed.
