— The magnetic field effect (≤2600 G) on the hydrogen abstraction of three anthraquinones in SDS micellar solutions was studied by steady‐state photolysis. The relative quantum yield of disappearance of quinones is significantly reduced (? 30%) in a magnetic field (2600 G). The observation was interpreted in terms of the radical pair model.
