## Abstract The dynamic elastic modulus of cellophanes has been measured by use of the resonant frequency of a 2 Γ 60βmm. strip of film in longitudinal vibration. The niodulus was computed from the resonant frequency length of specinieii, and the crossβsectional area determined from its resonant fr
Spectroscopic data can deliver force constants only if the exact chain conformation is known. For the longitudinal acoustic modes (LAM), however, simple linear chain models can be used to yield the effective longitudinal chain modulus from spectroscopic data of oligomer crystals. The model of p-coup
