Orientation of benzothiophene by a magnetic field in the isotropic liquid phase

The¹H NMR spectra of benzothiophene (a 2M solution in acetone), recorded on spectrometers with magnetic field intensities of 4.7, 9.39, and 11.74 T, were analyzed with high accuracy. By the use of the method of many spectrometers the spin-spin and dipole-diople coupling constants were obtained for all the pairs of protons, and the orientation parameters for the investigated molecule and , characterizing the anisotropy and asymmetry of the magnetic susceptibility, were obtained.M.
