Investigation of Electrode Processes and Double Layer Structure Using Visible/infrared Sum Frequency Generation
Abstract
dc:descriptionThe dependence of single crystal Ag azimuthal rotation on resonant SFG signal line shapes is examined using broad band multiplex SFG. Detailed fitting analysis of acquired spectra is used to extract data as a function of azimuthal rotation angle. Magnitude of non-resonant background, relative phase of vibrational modes, and other parameters are reported for varying levels of background suppression achieved by adjusting temporal overlap of incident laser pulses. The extracted fitting parameters show varying degrees of symmetry depending on the selected crystal face, and transformation of resonant signal line shapes from peak, dip, to derivative-shaped features is shown to be associated with changing intensity of non-resonant background signal.
