✦ Synopsis

A new pulsed EPR method for the determination of small hyperline and quadrupole interactions is described. The experiment is based on the burning of transient holes into an inbomogeneously broadened EPR line by exciting forbidden EPR transitions and detecting the hole pattern via an PID. The procedure allows the observation of all nuclear transition frequencies in a single experiment. The sensitivity of the new approach may exceed that of an electron spin echo envelope modulation experiment by up to an order of magnitude.

Radiofrequency continuous wave EPR spectrometers for detecting and localizing free radicals in vivo in samples of 50-100 g have been developed. The main limitation of these EPR instruments is the slow acquisition time, and a sensible improvement is expected by the adoption of pulsed EPR techniques.
