Interchain Interactions Transition dipole in isolation. A transition dipole is directly related to the probability Two chain interaction. When two chains come into close proximity they there is Symmetrical interaction. Consider first the most symmetric configuration which is perfectlyH12 the term representing the interchain interactions. In the exciton approximation, the intermolecular interactions are assumed to be weak with respect to the intrachain interactions and the twochain excitedstate wave functions are taken as a linear combination of the isolatedchain unperturbed wave functions. For two identical chains, uC6& 5 1& interchain interaction

assumption that interchain interactions are of secondary importance and that most of the properties are governed by intrachain interactions. The need to incorporate the effect of the surroundings was clearly recognized in the field of nonlinear optics in order to rationalize the interconnection between the nature

The interchain interactions in the (SN) x polymer are discussed on the basis of onedimensional tightbinding SCF MO calculations of two chains of (SN) x.

Aug 14, 2001 Interchain hydrogenbonding interactions may facilitate translocation of K ions across the potassium channel selectivity filter, as suggested by synthetic modeling chemistry Juan C. Mareque Rivas, Harald Schwalbe, and Stephen J. Lippard PNAS August 14, 2001 98 (17);

Jul 12, 2001  Specifically, we will address the impact of interchain interactions within an organic layer on the transport and optical properties. These issues will therefore be more directly related to transistor and lightemitting diode applications; however, in all instances, the aspects related to interfacial charge or energy transfer processes will dictate the ultimate performance of a material in a given device.

material, interchain interactions must be taken into account to correctly describe the absorption spectrum. We show that the lowest energy feature in the pp region of the absorption spectrum is associated with an interchain absorption, the intensity of which is correlated with the degree of order in the polymer. Correspond

Abstract. Higher degrees of interchain interaction enhance the mobility of carriers at the expense of lower quantum efficiencies for electroluminescence. Taken together, the results reconcile much of the contradictory literature and provide a prescription for the optimization of conjugated polymer films for particular device applications.

In sociology, interaction frequency is the total number of social interactions per unit time. Interactions, or what Georg Simmel in his pioneering work called Wechselwirkungen, are the basis for society itself, according to Herbert Blumer.
