The proton NMR spectra of four deuteriated species of propylene ozonide and five of ethylene ozonide were analysed. The deuterium isotope shifts were 0.0140ppm (H gem to D), 0.0034ppm (H trans to D) and 0.0015 ppm (H cis to D) for propylene ozonide. The same trends were observed in ethylene ozonide.
## Abstract The effects of one‐bond and two‐bond ^2^H, ^13^CO and C^18^O isotope shifts on ^51^V shielding in various carbonyl–Cp–vanadium complexes (Cp = n^5^‐cyclopentadienyl) are reported and discussed with respect to the sensitivity of ^51^V shifts to bond extensions, and the rovibrationally av
## Abstract Proton and deuterium n.m.r. measurements in acetylacetone and 3,3‐d~2~‐acetylacetone are reported. Deuterium‐isotope effects on chemical shifts and keto–enol equilibria as a function of concentration in the two solvents triethylamine and pyrrole are determined. A strong solvent concentr
