## Abstract ^15^N and ^14^N NMR spectra show that there is no valence tautomerism involving the nitro group in nitro derivatives of benzofuroxan systems and that the __N__‐oxide function has a fixed position in the furoxan ring. Carbon chemical shifts of molecules with one, two or three furoxan rin

✦ Synopsis
Abstract
The ^1^H, ^13^C, and ^15^N shifts of 10 nitrogen‐containing bi‐ and triaryls are reported, including the coupling constants of the fluoro substituents with all nuclei. The proton and carbon resonances of the hetaryl structures are completely assigned. Copyright © 2001 John Wiley & Sons, Ltd.

The proton and carbon NMR spectra of eight 5-substituted acenaphthenes were obtained. The 13C chemical shifts of C-6 and C-2a of these compounds were compared with those of carbons located at structurally similar positions in 1-substituted naphthalenes (viz. C-8 and C-4). The 13C chemical shifts of
## Abstract The ^13^C and ^15^N NMR spectra of some __ortho‐, meta‐__ and __para__‐substituted methanesulphonanilides were recorded. Correlations of the ^13^C chemical shifts with the appropriate substituent chemical shifts (SCS) for monosubstituted benzenes were excellent and showed enhancement of
## Abstract Isotopically selective multiphoton dissociation of CHClF~2~ produced a mixture of ^12^C/^13^C isotopomeric tetrafluoroethylenes. Specific NMR parameters for each isotopomer and the composition of this mixture were obtained from ^13^C and ^19^F NMR spectra by spectral analysis using cons
