Characteristics of the first derivative of the XANES spectra. (a) E5 − E3 decreases with increasing X(CO2); this indicates a decrease in solvent polarity. (b) E5 − E3, unaffected by temperature. (c) Δμ, which reflects the size of the pre-edge peak, increases with X(CO2) for any given temperature. (d) Δμ decreases with increasing temperature for any given X(CO2). |
