โฆ Synopsis
An apparatus for low temperature acoustic medsurements is dewrrbed. The v:brational relaxation tlmcs ofCF4 have been determined between 183 K and 295 K, and the mechanism of vlbratlonal energy transfer in this molccuIe is discussed.

In this Paper the mechanical relaxation of polymers at low temperatures is investigated. The shear modulus, mechanical loss tangent, and damping behaviour of various amorphous and semicrystalline polymers are reported.
A collision model for thevibrational relaxation of hydrogen fluoride at low temperatures is proposed. Because of the contribution of a strong hydrogen-bond attraction, the molecules are considered to undergo oscillatory motion about their equitibrium orientations This motion is taken to be primarily
