Burning of spectral holes within the absorption band of the primary electron donor P in reaction centers of Rhodopseudomenus viridis is studied using selective excitation at 1014 nm and 1.7 K. A narrow (< I .O cm-') spectral hole with relatively weak electron-phonon and vibronic coupling is burned if the intermediary electron acceptor I is pre-reduced. The hole is broadened up to -9&150 cm-i if I is neutral and the electron-transfer chain is open. Broadening of the hole is discussed in terms of the fast (_ 7&l 10 fs) electron hopping between P* and P+BL-(BL, bacteriochlorophyll monomer in L protein subunit).

Based on an analysis of the VLBI observations performed in 1985-2010 within the framework of international geodetic programs on global networks of stations, we have obtained statistically significant corrections to the parameters of lunisolar tides-the nominal complex Love/Shida numbers. The new integral (frequency-independent) values of these parameters (inWe have detected a new effect of asymmetry in the horizontal tidal displacements in the direction of tectonic motions for 50 VLBI stations. We have determined upper limits for the influence of the frequency-dependent resonance effects whose estimation accuracy is limited by an abundance of close frequencies in their harmonic expansion. The influence of the transfer function for tides on the VLBI observations has turned out to be lower than the measurement accuracy. In future, positional GPS/GLONASS measurements are planned to be used to refine the resonance effects and the transfer function.
