Over the past decade, we have developed a spectroscopic approach to measure electric fields inside matter with high spatial (<1 Å) and field (<1 MV/cm) resolution. The approach hinges on exploiti...
Enzymes use protein architecture to impose specific electrostatic fields onto their bound substrates, but the magnitude and catalytic effect of these electric fields have proven difficult to quantify ...
The electric field created by a condensed-phase environment is a powerful and convenient descriptor for intermolecular interactions. Not only does it provide a unifying language to compare many differ...
Hydrogen bonds and aromatic interactions are of widespread importance in chemistry, biology, and materials science. Electrostatics play a fundamental role in these interactions, but the magnitude of t...
The role of electric fields in important biological processes such as binding and catalysis has been studied almost exclusively by computational methods. Experimental measurements of the local electri...
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...
The vibrational Stark effect (VSE) is the effect of an electric field on the vibrational spectrum. Typically, the largest change induced by an electric field is the linear frequency shift whose sensit...
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 (...
