Abstract

Ambient and low temperature 1H NMR spectra of a wide range of 3-and 4-monosubstituted, and some di-and tri-substituted C-nitrosobenzenes have enabled–NO substituent constants for the static and rotating ring molecules to be calculated. This has provided information on the shielding anisotropy of the NO group which in turn leads to the firm identification of the monomeric and dimeric solution species. In all cases lowering the solution temperature ...
