Abstract
Brillouin light and X-ray scattering have been used to investigate the dynamic structure factor of supercooled and glassy m-toluidine in the temperature range 34–303 K. In addition to the ubiquitous α-relaxation, evidence is given of a fast relaxation process active in the ns–ps time region. Data on activation energy of the fast process are obtained from the attenuation of longitudinal acoustic modes.
