The Pariser-Pam-Pople (PPP) method has revealed rich effects of the .n electron Coulomb interaction in (CH),. We discuss results obtained by the PPP model with the unrestricted Hartree-Fock (UHF) approximation and we show that concepts introduced by the PPP-UHF model give a new insight on Franck-Condontype electronically excited states in (CH),. In the first part of this paper, a brief review of the PPP-UHF model is given. We introduce phase and amplitude variables and show that solitons in the PPP-UHF model are phase excitations. In the second part of this paper, the effective Hamiltonian describing phase excitations is derived. We show that the phase Hamiltonian derived by the time-dependent Hartree-Fock approximation is the classical limit of the Hamiltonian derived by the bosonization method of Tomonaga, Luther, and others. The phase Hamiltonian has a family of new soliton solutions. These solitons are pure electronic excitations and correspond to the exciton and the magnon in (CH),.

“…There have been several attempts to obtain more precise information on the shape and spatial extension of the soliton wavefunction from the lineshape of the ESR signal [111]. But this essentially amounts to a deconvolution of the ESR line, and such deconvolutions are to a great extent not possible in an unambiguous way.…”

“…From the experimental point of view, the on-site Coulomb energy of the order of U = 3 eV is required to interpret arecent el'ectron nuclear-nuclear tripie resonance experiment [181] in terms of the neutral soliton. The above experiment indicates that the spin density at the odd and the even sites are of opposite sign and p+ = 0.06 and p_ = -0.02 where p is normalized with the spin density of the single electron.…”
