Adsorption of organosulfur species at aqueous surfaces: Molecular bonding and orientation

Article Abstract:

The surface properties of four tropospheric sulfur compounds, DMS, DMSO, DMSO2 and DMSO3, are examined at the vapor/H2O and vapor/D2O interface by sum-frequency spectroscopy (VSFS) and surface tension measurements. Strong and weak interactions with surface water are observed as well as reorientation of subsurface water molecules, which results in an increase in interfacial thickness.

Vibrational sum-frequency studies of a series of phospholipid monolayers and the associated water structure at the vapor/water interface

Article Abstract:

An experiment was done where the orientation and conformation of phospholipid monolayers and the structure of water associated with these monolayers adsorbed at the vapor/water interface were studied using vibrational sum-frequency spectroscopy. The studies show significant differences between the aqueous environments associated with the zwitterionic lipids and the charged lipids.

Hydrogen-bonding interactions at the vapor/water interface investigated by vibrational sum-frequency spectroscopy of HOD/H2O/D2O mixtures and molecular dynamics simulations

Article Abstract:

The experiments were done where vibrational sum-frequency spectroscopy (VSFS) and molecular dynamics simulation studies were done on a series of HOD/H2O/D2O mixtures at the vapor/water interface. The results obtained give insight into the molecular interactions in the interfacial region and an estimate of the interfacial depth probed.
