## Abstract The natural‐abundance ^13^C NMR spectra of __cis__,__cis__‐1,5‐cyclooctadiene monoepoxide and __cis__,__syn__,__cis__‐1,5‐cyclooctadiene diepoxide have been investigated over the temperature range of – 10 to – 180°C. Whereas the spectra of the former showed no dynamic NMR effect, two di

The uC NMR spectra of 24 1,3-dioxoIane derivatives are reported in an attempt to propose parameters for the C-2, C-4 and C-5 shifts from the %Me and 4-Me substituents, based on the ring stereochemistry. These parameters are obtained from simultaneous equations, and clearly agree with those Calculate
## Abstract The influence of substituents in a new series of 2__H__‐thiopyrans, 2__H__‐thiopyran‐2‐ones (thiones) and their thiazine analogues is examined by means of carbon (^13^C) and nitrogen (^15^N) NMR. A linear relationship is shown to exist between the chemical shifts (δ~13C~ or δ~15N~) of t
