Notes:
Raman spectra have been recorded for monodisperse and polydisperse samples of oligooxyethylene at several temperatures in the range 310-77 K. Four scattering peaks are found with frequency dependent on temperature. One at 92-80 cm-1 is unaffected by changes in chain length and is assigned to a lattice mode. The others are chain-length dependent and are assigned either to the longitudinal acoustical modes (LAM-1 and LAM-3)or, less certainly, to a transverse acoustical mode.
