The electric fields produced in folded proteins influence nearly every aspect of protein function. We present a vibrational spectroscopy technique that measures changes in electric field at a specific...
Vibrational Stark Effects of Nitriles II. Physical Origins of Stark Effects from Experiment and Perturbation Models
platinum titania catalyst flame synthesis one-step oxidation screening
2016/5/23
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...
Electric Field Effects on Kinetics of Electron Transfer Reactions:Connection Between Experiment and Theory
ADSORPTION KINETICS PROTEINS STRUCTURAL STABILITY
2016/5/23
The dependence of the rate constant for electron transfer on energy can be systematically studied by measuring kinetics in an applied electric field. General relationships are developed between observ...
