A detailed analysis of the -C NMR spectra of trans-stilbene and ten deuteriated trans-stilbenes has been undertaken. Some unusual deuterium isotope effects on carbon-hydrogen spin-spin coupling constants could not be explained by the ordinary primary and secondary isotope effects. The positive and n

Exchange of amide protons with deuterium results in changes of 13 C chemical shifts for carbon atoms near the site of substitution (CH{N and N{C|O). There is a measurable decrease in the isotopic shifts of CH{N for cycloalkylacetamides as ring size increases from 3 to 8 and for lactams as ring size

## Abstract A series of intramolecularly hydrogen‐bonded enamines, enols and enethiols with ester carbonylic, ketonic carbonylic, thioester carbonylic, nitro and sulphoxide acceptors were investigated to obtain ^13^C chemical shifts and deuterium isotope effects. Results from 33 new compounds and s
