174:, to measure the hyperfine splitting of the ESR line caused by the interaction with nuclear spins. This hyperfine splitting is the main source of the sensitivity of ESR to the chemical environment of the electron, and hence it underlies the broad applications of ESR in chemistry. Much of his work concerned the way this interaction term behaves as molecules tumble around in solution or undergo chemical reactions. He also investigated the special non-equilibrium ESR effects which are found as reactions take place.
