    • In a strict sense, L2,sample or r2,sample is not constant but dependent on ω2 in the OH stretching region because of the vibrational resonance. According to the calculation of the complex Fresnel factor and reflectivity, the phase shifts due to L2,sample and r2,sample are ∼π /10, which is about the size of experimental uncertainty of the phase. Thus, we limit our discussion to a large phase shift (π). The present (2) spectra were not normalized to the ω2 dependence of L2,sample and r2,sample.
