Reactions give solvents a kick During chemical reaction, the reorganization of solvent molecules not directly in contact with reactants and products is normally viewed as simple diffusion response. Wang et al. studied molecular six common reactions—including copper-catalyzed click reaction Diels-Alder reaction—with pulsed-field gradient nuclear magnetic resonance. They observed boost mobility relative to Brownian that was stronger for catalyzed reactions were studied. The mobilities verified microfluidic method. argue energy release produces transient translational motion reacting centers mechanically perturbs molecules. Science , this issue p. 537
