Consequences of Heterogeneity of Organic Molecules in Water: Enhanced Photodimerization of Olefins.

Summary: Have you ever noticed how oil and water don't mix? When scientists put certain chemicals into water, they don't spread out evenly. Instead, they bunch up into tiny clumps. Because these molecules are squeezed so close together in the water, they react to light much faster and join together much easier than they would in other liquids. It's like a crowded dance floor where it's much easier to bump into a partner!
