ABSTRACT
Surface-specific sum-frequency vibrational spectroscopy has been used to study the structures of the glycerol liquid/vapor interface. The results show that the molecules at the glycerol surface are highly polar ordered with the CH2 and CH groups projecting into the vapor and the OH group remaining at the surface or pointing into the bulk. More quantitatively, we have also determined how the CH2 groups of the molecules are oriented at the surface. © 2004 American Institute of Physics.
