Polarization rotation in a second harmonic reflection experiment from an isotropic surface of chiral Tröger base

Abstract : Polarization rotation in second harmonic reflection (ORD-SHR) is carefully investigated. After emphasizing the relevance of this technique for characterization of chiral molecules the optical activity of which arises from electric contributions, we bring an experimental demonstration with a specially synthesized acridine-substituted Tröger base, which displays very strong rotations. Measurements of this rotation for wavelengths spanning the absorption spectrum are satisfactorily reproduced by a model based on coupled, anharmonic oscillators.
