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.

## 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.

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).

## 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
