Abstract Single crystals of KHCO3 and KHSO4 have been investigated by solid state high resolution proton magnetic resonance techniques. These compounds may be considered as model systems for compounds that contain abundant quadrupolar nuclei (39K) with small magnetogyric ratio in ad-dition to the protons. Despite considerable line broadening resulting from 1H-39K dipole-dipole coupling, all four possible proton shielding tensors in KHSO4 , and an averaged shielding tensor for the two different proton sites in KHCO3 could be measured accurately. The results are analysed to determine the degree of ionization of the protons in the three types of hydrogen bonds occuring in KHCO3 and KHSO4.
