    Article Title: {X,Y}-Cyclacene Graphs with Next Nearest Neighbor Interactions
    Article Snippet: ARTICLE HISTORY Received December Accepted February KEYWORDS Cyclacene graphs; eigensolutions; next nearest neighbor (nnn) interactions; total π -electron energy and HOMO–LUMO gap Introduction Cyclacene, also known as cyclopolyacene, is a cylindrical polyacene composed of hexagonal rings, and being the basic units of many important conjugated hydrocarbons, like fullerene, nanotubes, nanotories, etc., it becomes an importantmaterial for experimental and theoretical studies (1–13).. Fairly recently, Tüker andGümüs (14) reviewed in details several properties of both unperturbed and unperturbed cylacenes in the attempts to synthesis such compounds.. The eigensolutions (and hence eigenvalues and eigenvectors) of any graph are important quantities for predicting physicochemical properties of the concerned molecules/systems (15–17).

    Article Title: Revisiting Kassman’s path deletion procedure for the eigenvector coefficients of molecular graphs
    Article Snippet: Kassman’s path deletion procedure for the determination of eigenvector polynomials (EPs) and hence the eigenvector or molecular orbital (MO) coefficients of a molecular graph is revisited with required proofs and illustrations.. As EPs vanish for n-fold degenerate eigenvalues, the calculation of eigenvector (MO) coefficients for such an eigenvalue requires (n-1)-th derivative of each EP.. The eigenvector coefficients for other degenerate eigenvalues are then obtainedby exploiting the inherent symmetry of the molecular graph.

    Article Title: Practical Tight-Binding Hückel-Like Modeling of Electronic Properties of Saturated Hydrocarbons: On σ-Aromaticity of Cyclopropane and Correlations of Alkane Ionization Energies and Enthalpies of Formation Corrected for Protobranching.
    Article Snippet: This testing of σ-aromaticity in cyclopropane and protobranching in alkanes via a Hückel-Like Model proposed by Klein and Larson is expedited by mirror-plane fragmentation per the method of McClelland originally developed for conjugated polyenes.. Alkane carbon sp orbitals are represented by edge weighted tetrahedral stellate graphs connected to hydrogen orbitals.

    Article Title: Facile calculation of Hückel molecular orbital eigenvalues of short (n,0) nanotubes
    Article Snippet: A method for quickly calculating the Hückel molecular orbital eigenvalues and other properties of two series of open-ended single-walled nanotubes is given.. Circumscribing generates series of related nanotubes and mirror-plane fragmentation and embedding of larger molecular graphs gives smaller subgraphs resulting in substantial simplification of eigenvalue calculations.. Molecular graphs with greater than two-fold symmetry are at least doubly degenerate in about two-thirds of their Hückel molecular orbital eigenvalues and that the right-hand mirror-plane subgraphs only contains one set of these doubly degenerate eigenvalues.

    Article Title: Assessment of the Performance of the Bond Resonance Energy, Circuit Resonance Energy, Magnetic Resonance Energy, Ring Currents, and Aromaticity of Anthracene, Biphenylene, Phenalenyl, and p -Terphenyl.
    Article Snippet: This paper contributes to the further understanding of bond resonance energy (BRE), circuit resonance energy (CRE), and ring currents (RC = I) as indices for the measure of local ring aromaticity and topological resonance energy (TRE) and magnetic resonance energy (MRE) as indices for the measure of global molecular aromaticity.. Calculations of ring currents in the 3-ring polycyclic hydrocarbons of anthracene, biphenylene, phenalenyl, and pterphenyl are demonstrated.. This comparative study provides new molecular insights.
