✦ Synopsis

It has been well established that the 13 C chemical shift of ring carbon atoms normally moves to higher field with decreasing ring size both for carbocyclic 1 and saturated heterocyclic2 compounds. Recent work3 has shown that in compounds where two of the cyclo-

## Abstract The ^13^C^13^C spin–spin coupling constants in natural abundance oxetane, thietane, cyclobutanone, bromo‐and chlorocyclobutane have been measured. Furthermore, the ^13^C isotope‐induced changes in the chemical shifts of the different ^13^C nuclei in the molecules mentioned above are re

## 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

Using a topological parameter, A,, to characterize the effects of a variable mono-or polyalkyl environment, R, on widely varied types of "C sites gives rise to a homogeneous description of their chemical shifts over the entire range of 613C variation (220 ppm/TMS). The proposed model, 613C= w,A,+q,

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
