Polarized Raman spectroscopy has been used to measure the deuterium isotope effect, ∆pK = pKD2O– pKH2O, for the second ionization constant of carbonic acid in the temperature range of 25 oC to 125 oC, CO3-2+ D2O ⇋ DCO3- + OD-. Results for the light water pK dependence on temperature were compared to literature, confirming the reliability of the method.
