Abstract A new experiment, called soft ESEEM, that allows the indirect detection of nuclear transitions via a pulsed version of electron spin double resonance is proposed. The transfer of coherence between two connected transitions, one allowed and one forbidden, by means of a pair of selective pulses permits also the measurement for extremely large hyperfine coupling constants.
