## Abstract The self‐association of pyrimidine and its methylated derivatives was studied by measuring the concentration‐dependent changes in proton chemical shifts in deuterium oxide at 35°C. The data were analysed by a dimer model with two parameters. The equilibrium constants give an increasing
## Abstract The ^1^H NMR spectrum of chlorpromazine hydrochloride was fully assigned at 400 MHz. Similarly, the ^13^C NMR spectrum was assigned unambiguously using two‐dimensional NMR. Measurements of chemical shift as a function of concentration in D~2~O showed appreciable changes of shift of both
## Abstract The monomer–dimer equilibrium of retinoic acid in carbon tetrachloride was studied by ^1^H and ^13^C NMR spectroscopy. The dimer dissociation constant at 24°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
