(Left to right) Water-association band spectra distance (SDWATER) referred to the spectrum measured at 20 K versus temperature; CO stretching band spectra distance (SDCO) versus temperature; plot of the SDCO versus the SDWATER. Data refer to the very dry samples. The very good reproducibility of the data points obtained when cycling the temperature indicated that data points are taken under thermal equilibrium (data not shown; see, e.g., Giuffrida et al. (29,30)). Note the scale difference among Figs. 5–7.
