摘要：

Non-linear ESR schemes can be devised with high sensitivity to slow time scales. The glass transition of a polymeric mesophase is investigated by longitudinally detected ESR (LODESR) spectroscopy. By direct linewidth measurements the orientational correlation time of paramagnetic probes is measured. The temperature dependence is found of the Williams-Landen-Ferry form.
