Abstract

Comparison of the room and low temperature (203 K) ^13^C NMR spectra of 3‐cis‐bicyclo[4.4.0]decanone and its 2,2,4,4‐tetradeuterio isotopomer provides information about the deuterium isotope effect on the conformational equilibrium in this compound. Four‐bond low field deuterium isotope effects on some carbon chemical shifts are observed. These effects can be used for unambiguous assignment of the ^13^C lines to carbon atoms in alicyclic compounds.

## Abstract Long‐range deuterium isotope effects on ^13^C chemical shifts, ^__n__^ΔC(OD), were studied in the intramolecularly hydrogen‐bonded purpurogallins (benzotropolones). A very large long‐range isotope effect from the hydrogenbonded 4‐OH(D) is observed over six bonds at C‐7. Further, long‐ra
