Abstract
We explain the absorption line and resonant Raman lines splittings together with the selection rules at low temperatures in polydiacetylene polymer crystals in terms of a chain-pairing mechanism arising from side-group interactions between the conjugated carbon chains. The symmetry of the pairing configuration has drastic effects on the one- and two-photon absorption spectra.Keywords
