We report ionic strength-dependent phase shifts in second harmonic generation (SHG) signals from charged interfaces that verify a recent model in which dispersion between the fundamental and second harmonic beams modulates observed signal intensities. We show how phase information can be used to unambiguously sep. the χ(2) and interfacial potential-dependent χ(3) terms that contribute to the total signal and provide a path to test primitive ion models and mean field theories for the elec. double layer with experiments to which theory must conform. Finally, we demonstrate the new method on supported lipid bilayers and comment on the ability of our new instrument to identify hyper-Rayleigh scattering contributions to common homodyne SHG measurements in reflection geometries. In the experiment, the researchers used many compounds, for example, Sodium chloride(cas: 7647-14-5Reference of Sodium chloride)
Sodium chloride(cas: 7647-14-5) has been used for the preparation of tris buffered saline, phosphate buffered saline, MPM-2 (mitotic protein monoclonal 2) cell lysis buffer, immunoprecipitation wash buffer, LB (Luria-Bertani) media and dialysis buffer.Reference of Sodium chloride
