    • It has been shown (Wang, H.; Yan, E. C. Y.; Borguet, E.; Eisenthal, K. B. Chem. Phys. Lett. 1996, 259, 15) that the limiting length scale can be at least an order of magnitude less than the wavelength of light.

    • HRS arises from an instantaneous anisotropy that breaks the centrosymmetry present in an otherwise homogeneous solution.

    • note
    • The orientation information present in SHG is also lost in an HRS experiment, where orientational averaging allows only for the reporting of the average symmetry of individual (noninteracting) chromophores.

    • Polarization experiments (Figure 1 inset) also revel a dramatic difference between gold and silica colloids, where the ratio of vertically to horizontally scattered light for gold was found to be 2.2 ± 0.2 vs 22 ± 3 for silica (ref 19).

    • The enhancement mechanism could be similar to that previously observed for hyper-Raman scattering experiments (refs 28 and 29), but differences in experimental conditions and parameters make a direct comparison difficult.
