Zusammenfassung
The difference of 14N coupling in bicyclic and open chain hydrazine radical cations (I and II) ($\sim$1.2G) is smaller than the difference of the corresponding coupling consts. for the alkyl derivs. (III and IV)(5.7G). The results were rationalized in terms of differences in SiNSi and CNC bond angles. on SciFinder(R)
