Hydroxyl radicals in UV-exposed water reveal surprising reaction pathway

How do radicals form in aqueous solutions when exposed to UV light? This question is important for health research and environmental protection. For example, with regard to the overfertilization of water bodies by intensive agriculture. A team at BESSY II has now developed a new method of investigating hydroxyl radicals in solution. By using a clever trick, the scientists gained surprising insights into the reaction pathway. The findings are published in the Journal of the American Chemical Society.
