The 2nd International Conference on Hydrogen Atom Transfer (iCHAT 2017) will be held from July 2-6 2017 in Monteporzio Catone, a small village in the “Castelli romani” area about 20 km south of Rome. ...
Subpicosecond time-resolved absorption measurements at 77 K on two reaction center (RC) mutants of Rhodobacter capsulatus are reported. In the D(LL) mutant the D helix of the M subunit has been substi...
Stark spectra have been obtained in the region of absorption by the accessory bacteriochlorophylls (the B-band region around 800 nm) in Rhodobacter sphaeroides reaction centers. The Stark spectra in t...
Resonance Stark effects are nonclassical Stark effects associated with excited-state charge-transfer processes. The theory of resonance Stark effects developed in Part 2 of this series is generalized ...
In bacterial photosynthetic reaction centers, ultrafast singlet excited-state energy transfer occurs from the monomeric bacteriochlorophylls, B, and bacteriopheophytins, H, to the homodimer special pa...
Ultrafast singlet excited state energy transfer occurs from the monomeric bacteriopheophytin (H) and bacteriochlorophyll (B) chromophores to the primary electron donor or special pair (P) in bacterial...
We report the Stark spectra of the Soret, Q, and charge-transfer bands of deoxymyoglobin. The data show that band III has charge-transfer character but that the magnitude of the charge displacement is...
A theory of the resonance Stark effect data reported in part 1 (preceding paper in this issue) is developed. The model used involves a weak charge resonance interaction between the excited state of an...
Higher order Stark spectroscopy has recently been introduced and applied to characterize the electrooptic properties of chromophores in bacterial photosynthetic reaction centers.1 In the course of the...
Stark (electroabsorption) spectroscopy can provide quantitative information on the change in dipole moment and polarizability for an electronic transition. In the case of mixed-valence transitions, th...
Ultrafast singlet excited state energy transfer occurs from the monomeric chromophores to the primary electron donor or special pair in photosynthetic reaction centers. The mechanism of this process h...
The quantum yield of the initial charge separation steps in bacterial photosynthetic reaction centers has been shown to be reduced in an applied electric field [Part I, Lao et al., J. Phys. Chem. 97 (...
The rates of electron-transfer reactions can be systematically varied by application of external electric fields. The electric field effect on the charge recombination rate constant of the state P[sup...
Extremely long distance electron transfer is observed in some photosynthetic reaction centers. For several charge recombination reactions, the rate appears to fall off much more slowly with distance t...
