Abstract

The influence of two-phonon-exciton interaction on the soliton characteristics in molecular chain with the cubic anharmonicity is investigated. It is shown that the soliton stability is enhanced by this interaction, especially in the region of the velocities close to the velocity of longitudinal sound waves.
