    • The standard transmission data were obtained using BL 10-1 at SSRL and the SXTM transmission measurements using BL 11.0.2 at the ALS. Both measurements were conducted with an energy resolution of 0.1 eV.

    • 4 was adsorbed below 35 K on Pt(1 1 1) using a pulsed gas-delivery system. Coverage and cleanliness was checked using XPS, in particular to avoid CO contamination. The XAS spectra were recorded in AEY, using a 7 eV wide energy window centered around the C KLL Auger line at 262 eV. A SCIENTA hemispherical analyzer with pass energy 300 eV and 0.8 mm slits was used with the electron analyzer oriented perpendicular to the E-vector of the incoming photons in order to suppress direct photoemission peaks.

    • note
    • 2O ice films of around 80 layers were grown on the clean Pt(1 1 1) surface at 100 K at a deposition rate of 0.08 layers/s using a pulsed gas delivery system. Crystalline ice was obtained by isothermal heating at 150 K of the amorphous film and changes in the water desorption rate were monitored through mass spectrometry.

    • h sample was made from the amorphous sample by slowly heating it to about 150 K. Crystallization was observed to be complete after approximately 30 min. Both ice samples were approximately 200 nm thick.

    • -1 and p-polarized light were used for IRAS measurement. Notably, no absorption peak of the ice film was observed in s-polarized IRAS due to the surface dipole selection rule for metal surfaces.

    • 2(1 1 1) surface at 100 K. A monolayer is assumed to be equivalent to the amount of a single layer of water on Ni(1 1 1) as calibrated by XPS and where the same dosage procedure was applied. Crystalline ice layers were prepared by annealing amorphous layers to the indicated temperatures. X-ray absorption spectra were recorded in partial electron yield (PEY) mode with a resolution of 0.1 eV.

    • note
    • 2O + OD layer was obtained when the (2 × 2)-O coverage was 0.23 ml. At 0.09 ml (2 × 2)-O, however, the obtained coverage was 0.67 ml and by extending the heat ramp to 166 K the obtained coverage became 0.58 ml.
