Ultrafast photochemical reactions in liquids occur on similar or shorter time scales compared
to the equilibration of the optically populated excited state. This equilibration involves the …

This review deals with dynamics of water molecules in the hydration layer that surrounds
selfassemblies and proteins in aqueous solutions. This topic has not only seen a vigorous …

THE timescale of the response of solvent molecules to electronic rearrangement of solute
molecules has a critical influence on the rates of chemical reactions in liquids1–10. In …

Two-dimensional (2D) optical spectroscopy utilizing multiple ultrafast coherent laser pulses
in the infrared or UV-vis frequency range has been used to study protein structure and …

Because of its unique properties, water drives many natural and biological processes. While
a detailed understanding of its precise role is still being unravelled, it is clear that the …

Enzymes play a key role in almost all biological processes, accelerating a variety of
metabolic reactions as well as controlling energy transduction, the transcription, and …

Density functional theory (DFT) methods for calculating the quantum mechanical ground
states of condensed matter systems are now a common and significant component of …

▪ Abstract Experimental and theoretical studies of polar solvation dynamics and spectral line
broadening are described. Photon echo and fluorescence Stokes shift experiments are …

Recent experiments, theories, and computer simulations aimed at elucidating the dynamics
of solvation in polar liquids are critically reviewed.

Polar solvents often exert a dramatic influence on reactions in solution. Equilibrium aspects
of this influence involve differential solvation of reactants compared to the transition state …
