Interaction of polyatomic molecules at low energies

The authors discuss a theoretical model of collective vibrational states, excimoles, that arise in polyatomic molecules interacting at low energies. It is assumed that molecules have substructures composed of identical periodically ordered diatomic dipoles. Accumulation of excimoles occurs in the substructures when molecules slide over a surface containing molecules of the same kind at a velocity below the Bohr one. An analytical formula is presented for the probability of molecule dissociation in this process. A possible spectrum range of dissociation fragments is discussed.
