Chlorine-35 nuclear quadrupole resonance spectra of chlorodiazines
Abstract
The 35CI n.q.r. spectra of 17 chloroazines have been measured. The results are compared with values predicted by empirical methods. In general, they show it is not possible to extrapolate from chloropyridine to chlorodiazines since the effect of the additional nitrogen is mainly inductive rather than conjugative. Large solid-state splittings are observed in some chloropyridazines.
