The use of the 13 C satellites in the proton NMR spectra of systems providing deceptively simple spectra is suggested and demonstrated for the determination of molecular geometry using NMR spectroscopy of oriented systems. The r α structure of phenyl isothiocyanate has thus been determined. The spectrum without the 13 CH satellites does not provide sufficient independent dipolar couplings to determine the relative arrangements of protons and the order parameters.
