Abstract
Rayleigh-Brillouin scattering spectra of the molecular glass former sa lol were combined with ultrasonic measurements to evaluate the non-erg odicity parameter of mode coupling theory f0(T). A weak cusp was found at a temperature T(c) = 275 K in reasonable agreement with the temper ature found by other methods.
