Abstract
1H‐N.M.R. Spectroscopic Investigations on Innermolecular Mobility of Substituted 1,3‐DiazabutadienesTwo isomerization processes in substituted 1,3‐diazabutadienes can be observed by the method of dynamic n.m.r. spectroscopy. From coalescence phenomena the free activation enthalpies ΔG± are determined and discussed with regard to substituent effects and solvent dependency.Keywords
