摘要
Based on both the definition and experimental data, we propose that the inverse of the Grüneisen parameter γ is directly related to the fractal dimension. Scaling behavior of vibrational frequency versus volume extends over large distances via constructing the relation of the Grüneisen parameter to the interatomic force constant for some alkali halides with an NaCl structure. In particular, these alkali halides should possess a universal class with γ = 1.245.
