Nuclear Magnetic Resonance Spectroscopy. Analysis of the Proton Spectrum of 7,7-Dicyanonorcaradiene

Complete analysis of the six-spin proton high-resolution n.m.r. spectrum of 7,7-dicyanonorcaradiene (I) at room temperature has been achieved at 60 and 100 Mc.p.s. Only one set of parameters with all of the couplings having a positive sign gave good agreement between observed and calculated resonance lines at both frequencies.
