Two-photon absorption circular dichroism: a new twist in nonlinear spectroscopy.
Herein we report on the full experimental measurement of the two-photon absorption circular dichroism spectra of (S)-(-)-1,1'-bi(2-naphthol) and (R)-(+)-1,1'-bi(2-naphthol), their analysis, and theoretical support. The finding of new nonlinear optical fingerprints in chiral molecules offers new opportunities in the recognition and understanding of optically active systems in regions where CD could present strong limitations.
