✦ Synopsis
C-nitroso compounds are of considerable interest in chemistry because of dimerization and cis-trans isomerization of the dimer. The climer formation has rf~. 26
The two kinds of exchange processes do not interfere and can be treated independently by the NMR line-shape method. Currently we carry out detailed kinetic and mechanistic studies along these lines. Since these reversible processes fall in the NMR time-scale, suitable chemical relaxation methods may also provide a useful tool in studying the kinetics of aromatic C-nitroso compounds. Some steps in the direction of such studies have already been taken in our laboratories. We hope to report in the near future the results of these studies.
