A picosecond timehyphen;domain light scattering technique is used to study the viscoelastic KNO3ndash;Ca(NO3)260:40 glasshyphen;forming liquid mixture. By using scattering angles between 1.92deg; and 85.67deg;, acoustic frequencies from 50 MHz to 4 GHz are sampled. Together with existing ultrasonic and Brillouin scattering data, a temperaturehyphen;dependent distribution of relaxation times is found to be well fit with a Colendash;Cole distribution whose width changes from several decades in the glassy state to nearly single relaxation time in the highhyphen;temperature liquid state. The characteristic relaxation time is found to obey the Vogelndash;Tammannndash;Fulcher law withT0=338 K.
