✦ Synopsis

The qu&eIastic n6.Xllron scattering peaks obtained from polytefrabydrofuran and its pcrdeutko analogue have been observed in soIution in CS2. Thus the incoherent and coherent components can be separated-The resultsdo not support the Rouse model of polymer chain dynamics but the Zimm model, which includes hydrodynamic interactions. may apply.
