ABOUT MATERIALS WITH NEGATIVE DIMENSION OF VIBRATIONAL SPECTRA
Abstract
It was found that intermodular vibrational spectra of Van der Waals clusters, calculated by ab initio methods have power-law dependence on the frequency, like crystalline bodies. However, the argument df of their spatial dimension, in contrast, for example, from the three-dimensional wave space df = 3 (the Debye law), take the values df<1, df=0, and may even be negative. Substances with dimension of spectra df <0, previously were not found.
