High-σ and Low-σ Polyacetylene: A Comparisonease in conductivity due to mechanical stretching, the conductivity anisotropy reaches higher values and the fibrillar interior of the samples is more homogeneously oriented. However, the results indicate that differences in the degree of fibrillar orientation can explain only part of the differences in conductivity between different samples.

Grundlagen der Informationssicherheit,counterion present. A screened version of the Ohno effective Coulomb potential is used in parallel to the usual Ohno potential in order to incorporate the additional screening due to electrons on neighboring chains. This screening is observed to cause a more localized excitation, i.e. to increase the electron-hole interaction.

Informationssysteme der Produktionsults hint to the occurrence of non-planar conformations and seem consistent with the experimentally demonstrated flexibility of the polymeric chains and the computed low value of the rotational barrier.
