1. Wiener numbers of pericondensed benzenoid hydrocarbonsSandi Klavžar, Ivan Gutman, Amal Rajapakse, 1997, izvirni znanstveni članek Opis: Using a recently developed technique for the calculation of the Wiener number (W) of benzenoid systems, we determine explicit expressions for W for several homologous series of pericondensed benzenoid hydrocarbons. An elementary proof for the correctness of the used method is also included.

2. On algebraic and geometric Kekulé structures in benzenoid rotagraphsAnte Graovac, Damir Vukičević, Janez Žerovnik, 2006, izvirni znanstveni članek Opis: Recently introduced algebraic Kekulé structures (AKS) describe the ▫$\pi$▫-electron distribution within rings of a conjugated network. The ratio of the AKS countto the classical Kekulé structures count was studied in benzenoid rotagraphs. By considering three representative classes of such rotagraphs, it was shown that this ratio tends towards either 1 or 0, or its value lies between 0 and 1.
