The nature of H-bonding interactions is still far from being understood despite intense exptl. and theor. studies on this subject carried out by the leading research centers. In this paper, by a combination of unique high-pressure IR, dielec. and volumetric data, the intramol. dynamics of hydroxyl moieties (which provides direct information about H-bonds) was studied along various isolines, i.e., isotherms, isobars, isochrones, and isochores, in a simple monohydroxy alc. (2-ethyl-1-hexanol). This allowed us to discover that the temperature controls the intermol. hydrogen bonds, which then affect the intramol. dynamics of O-H units. Although the role of d. fluctuations gets stronger as temperature rises. We also demonstrated a clear connection between the intra- and intermol. dynamics of the associating liquid at high pressure. The data reported herein open a new perspective to explore this important aspect of the glass transition phenomenon and understand H-bonding interactions at varying thermodn. conditions.
