## Abstract The OH chemical shift of the enol form of nitromalonamide is found at 18.9 ppm both in DMSO‐__d__~6~ and in DMF‐__d__~7~ indicating a very strong hydrogen bond. The OH chemical shift is insensitive to temperature changes. Contrary to the large OH chemical shift, a small two‐bond deuteri

Over 100 isotope effects on "C chemical shifts were determined in a series of deuteriated cis-stilbene isotopomers. The magnitude and sign of these effects depend on the position and the number of deuterium atoms in the molecule. The variations in two-and three-bond effects were rationalized by ste

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
