Computation of Unique NMR Parameters for ABC Systems with the Aid of C13–H Satellite Spectra

Abstract
Theoretical analyses of proton magnetic resonance spectra of ABC systems have on occasion resulted in more than one set of acceptable parameters. It is proposed that such ambiguities can be eliminated by requiring the parameters to satisfactorily predict not only the normal spectral patterns but also those of the C13–H satellite spectra. This procedure has been successfully applied to tetravinylsilane and acrylonitrile.
