✦ Synopsis

Abstract

The reduced Raman spectrum of amorphous Te consists of broad maxima at 90 and 157 cm^−1^. The spectrum reflects the vibrational density of states and is interpretable in terms of disordered chains. The highest vibrational energies of the disordered chains are higher than the corresponding energies of the ordered chains in crystalline Te. The higher vibrational energies in the amorphous form are due to the reduced effectiveness of long range forces which tend to depress vibrational energies in the crystalline form.
