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