L'influence de la fréquence du courant électrique de chauffage par effet Joule sur la chaleur spécifique a été étudiée au voisinage de la transition vitreuse du glycérol. Une équivalence temps-température est proposée, le temps de relaxation moyen correspondant à une énergie d'activation de 2,1.104 K. A la limite des hautes fréquences, C - C∞ décroît suivant une loi de puissance en 0,28.The frequency dependence of the specific heat of glycerol at the glass transition has been measured. A time-temperature equivalence is found - the mean relaxation time having an activation temperature of 2.1.104 K. In the high frequency limit C - C∞ decays as a power law with exponent 0.2
