ABSTRACTUsing 632.8, 514.5, 488.0, and 457.9 nm as wavelengths of excitation, Raman spectra have been observed for single crystals of the polydiacetylene of - (CH2)4OCONHCH(CH3) 2 (Poly-IPUDO). The hysteresis effect observed for the thermochromic shift in the Raman spectra is supported by data from repetitive temperature cycling in differential scanning calorimetry.
