摘要

Abstract: High-resolution deuterium NMR spectra of styrene-ad, styrene-d,, 1- vinylnaphthalene-ad, and 2-vinylnaphthalene-ad in hydrocarbon solvents were recorded at field strengths of 14.1 1 to 14.57 T. Quadrupolar splittings were observed as a consequence of magnetic field-induced alignment of the solute molecules. The magnitudes of the splittings were used to calculate the average value of sin2 a, where a is the dihedral angle between ...
