Pyridazine, pyrazine and substituted pyridazines have been studied by proton magnetic resonance spectroscopy. The spectra of pyridazine and pyrazine were analyzed completely with the aid of information obtained from the C13-satellites (in natural isotopic abundance), whereas the spectra of substituted pyridazines were analyzed easily by the usual ...
