Un exemple d'utilisation spécifique de la RMN du carbone-13: les transferts protoniques sur centre carbone

A new method is described to study proton transfers on a carbon centre by means of carbon-13 N.M.R., using non-enriched samples, and without proton decoupling. As an example, the proton exchange rate k between dimethylsulphoxide and its conjugate base, the dimsyl ion, is measured at 25°C : k = 22·1 M-1 s-1.
