    Notes: Summary We demonstrate that a hybridization of Frenkel and Wannier-Mott excitons in parallel neighbouring organic and semiconductor quantum wires may occur due to the resonance dipole-dipole interaction between the wires. The hybridization might be especially efficient for excitons with small wave vectors along the wires when the transition dipole moments of excitons are oriented perpendicular to the wires. The hybrid wire excitons may possess both a large radius and a relatively large oscillator strength which could be important in non-linear optics.

    Notes: Abstract The configurational properties of a molecular chain are investigated. The chain consists of rigid rod segments, which are consecutively correlated. This correlation is described by a two-state model. In the first state, neighboring segments are freely hinged togethers whereas in the second state they are parallel. The partition function and the force-extension relation are calculated. They show significant differences as compared to the usual results for a freely jointed chain. Thus the experimentally observed force-extension relation of polymeric networks buil up of such chains might be affected.
