Proton and carbon-13 spectra of benzyl compounds of the general formula (C,H,CH,),X with a large variety of X substituents have been measured. While a linear relationship between the CH, chemical shift and the substituent electronegativity was found both for lH and lac, large deviations from lineari

Abstract
^13^C NMR data for forty 1‐pyrroline 1‐oxides, six 2H‐pyrrole 1‐oxides, three 2H‐pyrroles, eight 1‐pyrrolines and four related oxaziridines are reported. Comparisons are made with respect to the five‐membered ring carbons, subdividing them as the central carbons, the nitrone carbon and the gem‐dimethyl‐substituted carbon adjacent to nitrogen. The effects of substituents on the ring are also discussed.

## Abstract ^1^H, ^13^C and ^15^N NMR measurements (1D and 2D including ^1^H^15^N gs‐HMBC) have been carried out on 3‐amino‐1, 2,4‐benzotriazine and a series of __N__‐oxides and complete assignments established. __N__‐Oxidation at any position resulted in large upfield shifts of the corresponding
The 17O, 13C and 1H NMR spectra of a number of 1,2-dialkoxyethenes R1OCHxCHOR2 were recorded. The O atoms, in particular those of the E forms, are strongly shielded relative to the 17O nuclei of the corresponding alkyl vinyl ethers Moreover, in compounds of the type ROCHxCHOMe, the di †er-ROCHxCH 2
