” The Deuteron NMR Hahn Echo Decay in Polymer Melts.”
A self-consistent approximation beyond the Redfield limit and
without using the Anderson–Weiss approximation for Hahn Echo of
deuteron spins belonging to polymer chains undergoing reptation is
formulated. The dynamical heterogeneity of the polymer segments
created by the end segments, which is shown has a frequency nature,
is also taken into account . Recent experiments with polyethylene
oxide melts will be discussed.
