Effect of a ring on the cyclic conjugation in another ring: applications to acenaphthylene-type polycyclic conjugated molecules [PDF]
Journal of the Serbian Chemical Society, 2010 In a recent work, a method was developed for assessing the influence ief(G, Z0|Z1) of a ring Z1 on the energy effect of another ring Z0 in a polycyclic conjugated molecule G. Herein, a report is given of detailed numerical investigations of ief(G, Z0|Z1)
