Probing the Ag, Au, and Cu electrode/pyridine-α-hydroxymethyl biphenyl phosphine oxide isomer interface with SERS

- We study three pyridine-α-hydroxymethyl biphenyl phosphine oxide isomers using SERS.
- The SERS spectra are dominated by bands due to phenyl and pyridine ring vibrations.
- Geometry of these molecules depends on the electrode type and applied potential.
- We determine which molecular fragments are involved in the adsorption process.
