Surface of QDs is probed using visible-IR SFG and ppp signals dominate the polarization dependence. OA ligand have an orderly conformation on CdSe QDs ( Ì´ 2 nm). DR-SFG probes coupling effects of vibrations of ligands and electronic properties of QD core. Basic polarization rules are conserved and polarization dependence orientational analysis is applicable for this QD system.
