13C-nmr spectra of carbon dioxide in water are reported for a wide range in pH. Chemical shifts were determined for the following species: CO2(g), CO2(aq), HCO3−(aq), CO32−(aq). 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.

The guanidines 1, 4, 6, 8, 10, and 12 react with carbon dioxide in the presence of traces of water to give the guanidinium hydrogen carbonates 3, 5, 7, 9, 11, and 13. The crystal structures of the salts reveal the presence of centrosymmetric hydrogen carbonate ion dimers, which are connected by O-H・ ・ ・O hydrogen bonds. Additionally the cations are associated with the anions via N-H・ ・ ・O hydrogen bonds. The reaction of the N-(aminoalkyl)guanidine 14 with CO2 in the presence of traces of water affords a stable hygroscopic carbamic acid as the hydrogen carbonate salt 15. In the crystal structure of 15 the hydrogen carbonate ion is connected with the carbamic acid moiety by strong O-H・ ・ ・O hydrogen bonds
