Proton Magnetic Resonance in Hydrogen Bonded Dimers in Solids

Abstract

It is concluded through proton magnetic resonance that the positions of protons in boric acid crystals lie considerably away from the lines connecting two hydrogen bonded oxygens, in contrast to the case in potassium bicarbonate crystals, where protons are approximately on the oxygen-oxygen lines. The result is discussed in connection with the difference in strength of the hydrogen bond both cases.
