Surface-enhanced Raman scattering, electro- chemistry, and generalized two-dimensional correlation analysis methods were used to characterize phyllolitorin and a peptide derived from Pseudophryne guntheri (PG-L). Phyllolitorin and PG-L were deposited onto Ag, Au, and Cu electrode surfaces at different applied electrode potentials in an aqueous solution at physiological pH, and the orientations and adsorption mechanisms of peptides were determined based on the enhancement, broadening, and shifts in the wavenumbers of specific bands. On the basis of these analyses, specific conclusions were drawn regarding the peptide geometry and changes in the geometry that occurred when the electrode type and applied electrode potential were varied. The phyllolitorin and PG-L deposited onto the Ag, Au, and Cu electrode surfaces showed bands that were due to the vibrations of moieties in contact with or in close proximity to the electrode surfaces and were thus located on the same side of the polypeptide backbone. These moieties included the Phe and Trp rings, the sulfur atom of Met, and the amide bond. Variations in the arrangement of these fragments were observed with changes in the metal surface and the applied electrode potential.
