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.Keywords
