H and "C NMR studies of N-methyl-substituted hydroxamic acids, RCON(CH,)OH (R = CH,, C,H, and C6Hs), show that the series exhibits &-trans isomerism about the C-N bond. The Z/E ratio increases in the series CH, < C,H, < n-CsH,, < n-C,H,, for a given solvent, indicating that steric interaction betwee

## Abstract The high toxicity of diphenylarsinic acid, found in ground water and well water as a probable consequence of the inappropriate disposal of warfare agents, prompted us to study the reaction, monitored by ^1^H and ^13^C NMR spectroscopy, of the compound and its monophenyl analogue, phenyl
## Abstract Determination of the level and absolute configuration of 2‐hydroxyglutaric acid in a patient's urine is a method of diagnosing two metabolic diseases. Such a determination can be done with the aid of NMR spectroscopic methods. In this paper the careful interpretation of ^1^H and ^13^C N
## 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
Some derivatives of benzoxazolinone are studied by 'H and 13CNMR spectroscopy. 6-Crotonoyl (or cinnamoyl)-3methylbenzoxazolinones exist in the (8configuration and prefer the syn-planar conformation. 2,3-Dihydro-2,5-and 2,3dihydro -2,7 -dioxo -3-methylcyclopenta -[flbenzoxazoles are easily distinguis
