Figure 7: FTIR spectra for a Pt electrode covered with POAP in 1 M HClO4 solution in (a) water and (b) deuterated water. Sample potential: 0.7 V and reference potential: 0.1 V. P-polarized light, 100 interferograms. (c) FTIR spectrum obtained for a Pt electrode in 1 M HClO4 + 5 × 10−4 phenoxazine solution in deuterated water. Sample potential: 0.7 V and reference potential: 0.4 V. P-polarized light, 100 interferograms [49].
