The UV spectrum of linear C 6 has been observed, and correlates well with previous theoretical results. However, for the D 3h structure of C 6 , predicted to be more stable, no UV spectrum is available. Using a 9s5p1d/5s3p1d basis set, vertical excitation energies and oscillator strengths of both singlet and triplet states, for D 3h and D 6h structures...
The chemisorption of ethylene on Si 5+ clusters is investigated using MP2/6-31G*, higher-order correlation and DFT methods. Eight different approaches of C 2 H 4 to the quasi bipyramidal Si 5+ lead to a number of stable σ and π-adducts. It is shown that approach to the most stable σ-adduct (C 2 H 4 di-σ bonded to Si 5+ ) occurs...
