โœฆ Synopsis

Raman spectra of the black polydiacetylene single crystals TS6 and TS/FBS were recorded by means of a conventional Raman spectrometer with excitation in the near-infrared spectral region. We observed several sidegroup vibrations below 900 cm-' additional to the four strong vibrational modes which modulate the electronic states on the conjugated polymer backbone. The four strong bands of TS6 showed a splitting at low temperatures. The temperature dependences ofthese bands are discussed.

The 298 K Raman and reflection spectra of the polydiacetylene THD, a close structural variant of DCHD, are presented. The polymer double-and triple-bond stretch frequencies are 1485 and 21 I 1 cm-', respectively, and the lowest electronic transition peaks at 17600 cm-'. The reflection spectrum is mo
