Depolarized low-frequency data on neat liquid propylene glycol (PG) molecules and confined molecules in 25Åand 75Å pores of a controlled porous glass are presented. The goal is to elucidate the finite size effects on the dynamics of the hydrogen-bonded liquids, comparing their reorientational motion with the one of the same confined systems. The experimental data, performed as a function of temperature, allowed us to evidenciate the main role played by the strong dipolar interactions on the dynamics of hydrogen bonded liquids diffusing within nanoscopic pores.

Abstract
Depolarized low-frequency data on neat liquid propylene glycol (PG) molecules and confined molecules in 25Åand 75Å pores of a controlled porous glass are presented. The goal is to elucidate the finite size effects on the dynamics of the hydrogen-bonded liquids, comparing their reorientational motion with the one of the same confined systems. The experimental data, performed as a function of temperature, allowed us to evidenciate the main role played by the strong dipolar interactions on the dynamics of hydrogen bonded liquids diffusing within nanoscopic pores.File in questo prodotto:
