Abstract

A new technique which links the phenomenon of surface second harmonic generation (SHG) with circular dichroism (CD) spectroscopy is introduced. SHG spectra of chiral molecules (2,2'-dihydroxy-1,1'-binaphthyl) adsorbed at the air/water interface are dependent on the helicity of the incident circularly polarized beam. Moreover, the magnitude of the circular dichroic effect is 10 3 times greater than that observed in ordinary CD spectroscopy. Several factors including molecular orientation at the surface are considered as possible explanations for this enhancement
