N2 - Blue polydiacetylene films were prepared from the Langmuir-Schaefer (LS) and Langmuir-Blodgett (LB) films of the cadmium salt of 10,12-pentacosadiynoic acid, CH3(CH2)11{single bond}C{triple bond, long}C{single bond}C{triple bond, long}C{single bond}(CH2)8COOH, and the C{triple bond, long}C stretching modes of the Raman spectra of the LS and LB films were observed at 2068 and 2079 cm-1, respectively. These wavenumbers appeared to be sensitive to the packing of polymer chains. Most of the progression bands observed in the range of 1332-1182 cm-1 have been assigned to the CH2 wagging modes of the all-trans structure of the (CH2)11CH3 group.
