Abstract

15N-1H coupling constants can be measured over a large range by means of the Broadband-INEPT NMR-technique. These coupling constants are used to determine the positions of tautomeric equilibria of 2-(acetylmethyl)-azines with high accuracy.

Zusammenfassung

Mittels der Breitband-INEPT NMR-Technik können15N-1H-Kopplungskonstanten über einem weiten Bereich gemessen werden. Aus diesen Kopplungskonstanten kann die Lage der Tautomerengleichgewichte von 2-(Acylmethyl)-azinen mit großer Genauigkeit bestimmt werden.
