Abstract
Preliminary NMR studies on hydrogen bonding of carboxylic acid-carboxylate systems in an anhydrous, aprotic solvent are presented. In all cases, a low-field resonance (16-20 ppm) indicative of strong hydrogen bonding was observed. From these results, it seems probable that this characteristic downfield shift should be exhibited by all carboxylic acid-carboxylate systems in anhydrous, aprotic media.
