As known, the local-oscillation frequencies of light atoms in the ordering interstitial V$_{2}$D alloy are temperature dependent; they decrease with temperature lowering. This effect is ascribed to the ‘effective weighting’ of interacting D particles in the ordered phase. The aim of this article can be formulated as an attempt to estimate the influence of this ‘ordering-induced temperature-dependent weighting of light particles’ on the heat-capacity–tempera¬ture dependence for a given compound.
Key words: interstitial alloys, particle–particle interactions, local-oscillation frequencies.
