| Abstract: | Raman and infrared spectra have been recorded of water and heavy-water solutions of carbon dioxide, potassium bicarbonate, and potassium carbonate. The structures of the carbonate and bicarbonate ions and CO2 (aqueous solution) have been determined from a consideration of Raman and infrared data. The results reveal the presence of solvent effects in the carbonate and CO2 water solutions. No bands characteristic of H2CO3 were observed in the Raman spectrum of aqueous solutions of CO2. |
