Abstract

The orientational behavior of liquids confined in nanoporous glasses has been studied using ultrafast Optical Kerr Effect spectroscopy. We discuss the detailed microscopic behavior of a weakly wetting liquid (methyl iodide) and a strongly wetting liquid (acetonitrile) confined in these glasses. We demonstrate that the behavior of methyl iodide is dominated by geometrical effects while the behavior of acetonitrile is dominated by surface interactions. We provide evidence that molecular exchange into the bulk is an important channel for the reorientation of strongly wetting liquids at interfaces.
