Abstract
The lattice relaxation theory generalized by us to include the self-consistency of multi-electron states with lattice symmetry-breaking is summarized. The discrete symmetries and corresponding selection rules for both radiative and nonradiative processes are discussed. The theoretically calculated probability of nonradiative decay of an electron-hole pair into a soliton pair and that of an electron (hole) into a polaron as well as the probability of soliton pair photogeneration is compared with results of numerical and laboratory experiments. The resonance Raman scattering data of cis-polyacetylene are interpreted in terms of a bipolaron model. The parameters involved are determined directly from experimental data.
