Abstract
Absorption, fluorescence and resonant Raman spectra at 2 or 5 K of pol ydiacetylene poly4BCMU chains diluted in their single crystal monomer matrix are studied, and discussed in terms of the single conjugated po lymer chain electronic properties. Two new electronic transitions are observed below the intense exciton one. Absorption lines are very narr ow (less than or similar to 30 cm(-1) hwhm). Fluorescence is dominated by emission from the intense exciton state and its origin coincides w ith that of the absorption. Emission from the two other levels is also detected.
