Vicinal 3J(HH) and 3J( 13CH) coupling constants are reported for the two diastereoisomers of p-pbenylaspartic acid at various pH values. A comparison between these coupling constants and those expected from the possible conformations of these molecules allows configurational assignments to be made.

A detailed structural analysis of the copolyesterification in bulk without any external catalyst at 160ЊC between o-phthalic anhydride (P), oleic acid (O), and trimethylolpropane (T) with a mol ratio ([{COOH]/[{OH]) Å 0.70 has been carried out by high resolution 13 C nuclear magnetic resonance ( 13
## Abstract The ^13^C‐NMR chemical shifts of dicyanocobyrinic acid heptamethyl ester (**1**), an important corrinoid model compound, are correlated with those of some derivatives. Isotope effects on the ^13^C chemical shifts (over two to four bonds) are observed for the 10‐deuterio and the 10,13‐di
