Professor Timmel investigates spin-polarised radical pairs and their magnetic sensitivity. In this field of Spin Chemistry, her main focus has been centred on the study of the radical pair mechanism, speculated to lie at the heart of avian (night migratory) magnetoreception.
Fascinatingly, the formation of pairs of radicals inside the blue-light sensitive protein, cryptochrome, located in the bird’s retina is thought to lie at the heart of the phenomenon of magnetoreception. Using optical spectroscopy, Professor Timmel and her team have been able to show that the application of weak magnetic fields can indeed affect the yield of the reactions between light induced radicals inside cryptochrome proteins. Moreover, they have demonstrated the first so-called chemical compass which allows the determination of a magnetic field direction read out via the yield of a chemical reaction.
