13C NMR spectroscopic investigations were performed on aqueous solutions of diethylenetriamine (DETA) and carbon dioxide at 298.0 K. Systems with loadings ranging from 0 to 1.69 were studied. Results suggest that carbamate is one of the main species formed in the system at loadings below 1.0. At higher loadings (>1.0), it appears that dicarbamate is dominating and HCO3-/CO32- are also formed. No clear evidence was found of any tricarbamate species in the system.
