| Abstract: | Low-frequency Raman spectra are reported for monodisperse methylene-oxyethylene-methylene triblock oligomers. Assignments are made to the longitudinal acoustical modes (LAMs) of the oxyethylene block and the methylene block. The results for LAM-1 can be modeled by the vibrations of rods with perturbing forces and masses. The results for LAM-3 are not so readily modeled. |
