Spectral Hole Burning Studies of Photosystem II Reaction Centers: Excited State Structure, Charge Secomplexes of 2–4 orders of magnitude . As a result the level of detail available on the coupling of Chl optical transitions to intramolecular Chl modes and phonons (both delocalized and localized) is at an unprecedented level. Hole burning can also provide information on the early time (picosecon

Evidence for an Inhomogeneous Distribution of Reaction Centers on the Timescale of the Primary Electwest excited singlet state of the bacteriochlorophyll (BChl) dimer (P) to a neighboring bacteriopheophytin (BPh.) molecule roughly 10 Å away (edge-to-edge), followed by electron transfer over about the same distance from the BPh. anion to the primary quinone (Q.) The determination of the three-dimen

Analysis of Transient Absorption Data from Reaction Centers of Purple Bacterias. In order to understand the molecular mechanisms different spectroscopic techniques with very high time resolution are used. The most common spectroscopic method is the so-called “pump and probe” technique. A strong excitation pulse (wavelength favourable in the lowest absorption band of the speci

These differ in the role of the monomer bacteriochlorophyll (B) locatedbetween the primary donor (.P*) and a bacteriopheophytin molecule (H). In the two-step mechanism according to.P.B.H is the first radical pair formed. It develops with a rate constant k. and decays with the rate k. in the su

Reaction Center from Wild Type Y ,: Primary Structure of the L and M Subunits; Carotenoid and Detergural class for purple bacteria RCs. However differences have been reported, mainly at the level of the chromophores and of their interactions with neighbouring aminoacid residues . Detailed structural studies of RCs from various bacterial strains are therefore needed for determining the extent and the nature of these differences.

Analysis of Transient Absorption Data from Reaction Centers of Purple Bacteriaal pair P) starts the photosynthetic reaction which induces absorption changes in the sample. These changes are monitored by a second, properly delayed weak probing pulse of variable wavelength. The experiment yields the absorbance change ΔA as a function of delay time t. and probing wavelength λ..
