Optical absorption in the far infrared range for amorphous GaAs, SiC and Ge is investigated. Smallclusters in the context of dynamical disorder are considered. Average values of the absorption contributionsdue to both dynamical and structural disorders are introduced. In particular, an equation forthe spectrum due to dynamical disorder in amorphous SiC is presented
