| Popis: | 13C NMR spectroscopic data are reported for the s-triazolo-as-triazinones of five isomeric series. Comparison of their 13C chemical shifts and CH coupling constants allows the determination of the type of ring junction of the two heterocycles, as well as the predominant tautomeric form in each system. |
