We explore the exact soliton solutions of a model Hamiltonian that describes the nonlinear phase-amplitude excitations in a Peierls-Fröhlich condensate. Several novel features of soliton physics emerge: the existence of static multi-soliton bound states (solitonic "molecules") in the commensurate system and solitonic "molecular" lattice in the incommensurate system. We show that a discontinuous transition to an incommensurate ground state can occur. Implications of these results to doped polyacetylene and to the spin-Peierls system are discussed.
