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 mo

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
The 298 K Raman and reflection spectra of a single crystal TCDU polydiacetylene polymorph (TCDU-A') are presented. The lowest energy reflection maximum in TCDU-A\* is seen at 15900 cm-'. Raman and reflection spectra ofTCDU-A\* are similar to those for TCDU-A and thin film TCDU samples and significan
