Abstract: In this paper, applying the d. scaling idea to an associated liquid 4-methyl-2-pentanol used as an example, we identify different pressure-volume-temperature ranges within which mol. dynamics is dominated by either complex H-bonded networks most probably leading to supramol. structures or non-specific intermol. interactions like van der Waals forces. In this way, we show that the d. scaling law for mol. dynamics near the glass transition provides a sensitive tool to detect thermodn. regions characterized by intermol. interactions of different type and complexity for a given material in the wide pressure-volume-temperature domain even if its typical form with constant scaling exponent is not obeyed. Moreover, we quantify the observed decoupling between dielec. and mech. relaxations of the material in the d. scaling regime. The suggested methods of analyses and their interpretations open new prospects for formulating models based on proper effective intermol. potentials describing physicochem. phenomena near the glass transition.
