+ | ===== Time-resolved EPR spectroscopy ===== | ||
+ | |||
+ | Time-resolved EPR spectroscopy is a direct method for observing spin dynamics and electron spin polarization (ESP) during the formation of spin-polarised paramagnetic species, //e.g.// radical pairs or triplet states. The measured quantity is the temporal development of transient magnetization. The ESP determines the sign (absorption or emission) of the EPR signal. | ||
