Enhanced DR-FTIR spectra showing the effect of exposure to a humid CO2 atmosphere. The spectra of hydrated unexposed samples were subtracted from the spectra of the samples exposed to humid CO2, cancelling the effect of hydration on the samples. The assignments and characterizations of the peaks and bands, marked with IX in the spectra, are presented in Table 1.
