Time-resolved optical Kerr effect on a fragile glass-forming liquid: test of different mode-coupling theory aspects.

The dynamics of the fragile glass-forming liquid m-toluidine is investigated by time-resolved optical Kerr effect. A heterodyne detection technique allows to analyze the signal over four decades in time (10(-13) s to 10(-9) s), in the temperature range 250 K-295 K. The results of data analysis remarkably agree with the predictions of the idealised mode coupling theory (MCT). Some parameters related to that theory are here determined for the first time; also the material-dependent parameters lambda = 0.77 +/- 0.02 and T-c = 220 +/- 5 K can be independently and consistently determined from three different dynamical regimes.
