(a)–(k) Plots of the experimental ellipticity ε along the bond path (solid blue line) with the ϕref angle (solid red line) for all 11 C—C covalent bonds in OCN. (l) Ellipticity profile of a naphthalene ring taken from the literature (Farrugia et al., 2009BB18) indicating aromaticity by showing symmetrical distribution in ellipticity due to delocalization. The reference vector is normal to the plane of the ring in all cases.
