Isotopic labelling is widely used to unravel reaction mechanisms, but are conclusions from such studies always robust? Now, studies on the photolysis of CD3CHO reveal extensive isotopic scrambling before dissociation, which could have implications for our mechanistic understanding of some key aspects of atmospheric photochemistry.
