Spectral Hole Burning Studies of Photosystem II Reaction Centers: Excited State Structure, Charge Secomplexes of 2–4 orders of magnitude [2]. 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

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

However differences have been reported, mainly at the level of the chromophores and of their interactions with neighbouring aminoacid residues [5]. Detailed structural studies of RCs from various bacterial strains are therefore needed for determining the extent and the nature of these differences.

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..
