Abstract

The proton magnetic resonance spectrum of indazole in acetone has been investigated at 100 Mc/s. The spectrum is of the weakly coupled five-spin type. Transitions have been assigned on the basis of first-order theory and the experimental energy levels obtained. The analysis has been carried out with the aid of a digital computer using an iterative procedure. The presence of a long-range cross-ring coupling constant of magnitude approximately 1 c/s is reported.
