    We have studied the relation between the structural relaxation and the frequency dependent thermal response or the specific heat, cp(ω)c_p(\omega), in a supercooled liquid. The Mode Coupling Theory (MCT) results are used to obtain cp(ω)c_p(\omega) corresponding to different wavevectors. Due to the two-step relaxation process present in the MCT, an extra peak, in addition to the low frequency peak, is predicted in specific heat at high frequency.Comment: 14 pages, 13 Figure
