Soliton mechanism of ion mobility in incommensurate structures

A model of soliton ion mobility in one-dimensional incommensurate structures is considered as the possible mechanism of information transmission in molecular systems. Numerical calculations of the dependence of the diffusion activation energy on the concentration of mobile ions are performed. Experimental NMR data on lithium ion mobility in a model Li_xNbSe₃ (03) compound with a quasi-one-dimensional structure are presented. It is demonstrated that the proposed model describes the experimental data well.Institute of Inorganic Chemistry, Siberian Branch, Russian Academy of Sciences.
