A method to analyse two‐particle solitary waves is proposed. The effects of exciton—exciton interaction are omitted. The probability amplitude as well as the energies of bisolitons are found. The probability amplitude represents a modulated plane wave whose spatial part is expressed over the centre‐of‐mass coordinate. It is shown that bisolitons are bound states of two excitations.
