My group studies radical pairs – ubiquitous short-lived reaction intermediates whose chemistry is controlled to a large extent by electron and nuclear spins. Their defining characteristics are spin-selective reactivity and long-lived spin-coherences which result in reaction rates and product yields that are sensitive to magnetic interactions orders of magnitude weaker than the thermal energy per molecule, kT. Thus, manifestly quantum effects of weak magnetic fields on chemical reactions occur under conditions where the corresponding classical effects would be entirely negligible.
