The response of an intervalence band to an applied electric field, called an intervalence band Stark effect, is considered in detail. Because the application of an electric field to a symmetric mixed-...
Vibrational Stark effects, which are the effects of electric fields on vibrational spectra, were measured previously for the C−N stretch mode of several small nitriles, yielding difference dipol...
The vibrational Stark effect measures the effect of an external electric field on the vibrational (IR) spectrum of a molecule. This technique gives quantitative information on the sensitivity of a vib...
The electronic absorption spectrum of the homodimeric special pair in bacterial photosynthetic reaction centers is greatly modified when one of the bacteriochlorophylls is replaced by a bacteriopheoph...
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 (...
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...
Electron-transfer reactions are expected to be particularly sensitive to externally applied electric fields because of the presence of charge-separated, dipolar states, and the effects of the field on...
The effect of an applied electric field on the kinetics of the initial picosecond electron-transfer reaction in Rb. sphaeroides reaction centers has been measured in isotropic samples at 77 K. The net...
The temperature dependences of the reduction potentials (E degrees') of wild-type human myoglobin (Mb) and three site-directed mutants have been measured by the use of thin-layer spectroelectrochemist...
Prior to 1970there were several reports of the effects of magneticfields on chemical reactions, though there was muchrebuttal and retraction in this early literature (1-3). Since 1970, the number of r...
The aggregation rate of B-Lactoglobulin (BLG) was studied using turbidimetry and dynamic light scattering in the range 5.8 fixed ionic strength of 4.5 mM, and in the range 4.5 - 500mM NACl...
Eumelanin is a ubiquitous biological pigment, and the origin of its broadband absorption spectrum has long been a topic of scientific debate. Here, we report a first-principles computational investiga...
The vector correlations in Ca+HCl, Ca+DCl, and Ca+TCl reactions have been investigated by means of the quasi-classical trajectory calculations on PES constructed by means of multireference configurati...
Abstract: We consider a suspended elastic rod under longitudinal compression. The compression can be used to adjust potential energy for transverse displacements from harmonic to double well regime. T...
We propose a simple stochastic model which successfully explains the long coherence effects observed in photosynthetic Excitation Energy Transport (EET) by 2D photon echo experiments of G. S. Engel et...
