Nanosecond-resolved optically detected magnetic resonance: application to the study of triplet-state spin—lattice relaxation in benzil crystals

A zero field magnetic resonance spectrometer capable of investigating triplet states undergoing physical or chemical processes in tens of nanoseconds is described. The spectrometer employs pulsed laser excitation and time-resolved phosphorescence detection, together with very high power (1 kW) micro...

Description
Summary:A zero field magnetic resonance spectrometer capable of investigating triplet states undergoing physical or chemical processes in tens of nanoseconds is described. The spectrometer employs pulsed laser excitation and time-resolved phosphorescence detection, together with very high power (1 kW) microwave pulses. The technique was used to survey the triplet-state spin—lattice relaxation in benzil crystals at temperatures up to 217 K.
