Abstract
In this paper we calculate the vibrational spectra of classical, disor dered, glasslike chains using a perturbation method and examine the ef fect of various types of disordering on the spectra. The effects of lo calization are discussed, and the strong influence of this phenomenon on the convergence of the perturbation techniques is discussed. The in fluence of fluid damping on the lattice is also treated, thereby provi ding an approximate calculation for the damped oscillatory behavior of coagulated colloidal systems.
