Spin–spin coupling in cyclic systems : The topology of maps of the electonic current density induced by nuclear magnetic dipoles in ethane, cyclopropane and bicyclobutane is used to interpret 1 J (C,C) values in terms of classical electromagnetic theory. The results are not affected by the multipath coupling processes typically invoked in the literature. A contour plot of the Fermi‐contact coupling density for 1 J (C,C) in cyclopropane is depicted in the figure.
