Abstract
13C-NMR spectra of CO2 in water are reported for a wide range in pH. Chemical shifts were determined for the following species: CO2(g), CO2(aq), HCO3-(aq) and CO32-(aq) [g-gaseous, ag=aqueous]. A linear relationship was found between the shift of the 13C line and the fraction of carbonate ion calculated to be present, as well as between the ratio of the area under the 1067 cm-1 (carbonate) Raman peak to the sum of the area under the 1067 cm-1 and 1017 cm-1 (bicarbonate) peaks and the fraction carbonate.Keywords
