Abstract

The theoretical and experimental investigation of a new chiral second-harmonic generation technique that utilizes a counterpropagating optical geometry was conducted. The counterpropagating optical geometry employed here can effectively separate the chiral and achiral contributions to the SH emission, which cannot be easily accomplished under a copropagating geometry. The technique was applied to an experimental investigation of the molecular adsorption of (R)-(+)-1, 1-bi-2-naphthol to a planar-supported lipid bilayer of 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphotidylcholine. A strong chiral second-harmonic generation response was observed when a single enantiomer intercalated into the membrane, but showed no chiral response when equal concentrations of the enantiomers were present in the bilayer.
