Molecular, orientation and ordering of molecules on surfaces were examined using sum-frequency generation. Molecular ordering was observed for 1-hexanol adlayers in cyclohexane solvent at α-Al2O3 accompanied by reorientation of cyclohexane. For surfaces containing palladium nanoparticles prepared by atomic layer deposition, active site accessibility was examined as a function of preparation.
