SEIRAS Spectra of Interfacial Water at Cu, Au, and Pt Electrodes

Surface-enhanced infrared absorption spectroscopy (SEIRAS) data probes the O–H stretch band of interfacial water at Cu, Au, and Pt electrodes in various electrolytes. The dataset documents irreversible time-dependent changes at Cu and Au interfaces versus more reversible behavior at Pt, establishing protocols to isolate intrinsic potential-dependent solvation structures. The data is packaged in a 1.4 MB ZIP file.

Use Cases

• Analyze O–H stretch band spectra to compare interfacial water structure reversibility across Cu, Au, and Pt electrodes.
• Investigate how electrode potential affects interfacial solvation by isolating reversible spectral changes.
• Identify irreversible time-dependent changes at the electrode/electrolyte interface that could lead to misinterpretation of SEIRA spectra.
• Benchmark SEIRAS protocols for probing intrinsic potential dependence within the electrochemical double layer (EDL).

Strengths

• Data includes measurements from three distinct electrode materials (Cu, Au, Pt) enabling comparative analysis.
• Focuses on isolating reversible changes in interfacial solvation, a key methodological contribution.
• Explicitly addresses and documents a known pitfall (irreversible interface changes) in SEIRAS interpretation.

Limitations

• Dataset is small at 1.4 MB, likely containing summary spectra or figures rather than extensive raw time-series.
• Specific experimental parameters, spectral resolution, or replicate counts are not detailed in the provided description.
• Sample data and column structure are unavailable, limiting immediate computational analysis.
