Abstract
We show experimentally and theoretically that coupling between a spin system and the NMR probe, which is responsible for radiation damping, can also act to generate multiple-quantum coherences, even in molecules such as water which ordinarily have no multiple-quantum spectrum. We discuss the implications of this observation for solvent suppression sequences and for preparing nonequilibrium spin states.
