✦ Synopsis

A zero field magnetic resonance spectrometer capable of investigating triplet states undergoing physical or chemicai processes in tens of nanoseconds is described. The spectrometer emplo] s pulsed laser exitation and time-resolved phosphorcscence detection. together with very high power (1 I&Q microwave pulses_ The technique was used to survey the tripik4ate spin--bttice relaxation in benzd crystals at temperatures up ro 217 K.
