SUMMARY:Sum frequency generation spectroscopy of small molecules adsorbed 
 at interfaces - Mike Casford\, Department of Chemistry\, University of Cam
 bridge

CONTACT:Stephen Walley
DESCRIPTION:The adsorption of small molecules on surfaces in order to cont
 rol the physical and chemical properties of the interface is ubiquitous in
  both the industrial and natural world. This talk applies the interface sp
 ecific technique of Sum Frequency Generation Spectroscopy (SFG) to determi
 ne the orientation and conformational ordering of a selection of small mol
 ecules at a model biological interface (cholesterol on a hybrid bilayer me
 mbrane) and an industrially relevant interface (a friction reduction addit
 ive at the metal/oil interface). This talk highlights the ability of SFG t
 o probe molecular conformation at a variety of buried interfaces that are 
 difficult to access in situ with other surface analytical approaches.
