A study of a common chemical reaction in a mixed alcohol-water solvent revealed that the transition state—the fleeting, high-energy moment when reactants turn into products—is surrounded by a unique, layered shell of solvent molecules. Understanding this microscopic solvation environment is crucial for designing better solvents to control the speed and outcome of industrial chemical reactions.
