## Abstract Chemical shifts of Hβbonded protons in tetrabutylammonium hydrogen maleate and 14βsubstituted picolinic acid __N__βoxides have been measured in a number of dry solvents, of different activity, in order to distinguish between symmetrical single minimum and asymmetrical hydrogen bonds. In
## Abstract The monomerβdimer equilibrium of retinoic acid in carbon tetrachloride was studied by ^1^H and ^13^C NMR spectroscopy. The dimer dissociation constant at 24Β°C was determined to be 0.38 mM from a fit of the changes in the carboxylic acid carbon chemical shift as a function of concentrati
