Elucidating the ${}^1$H NMR relaxation mechanism in polydisperse polymers and bitumen using measurements, MD simulations, and models

Philip M. Singer, Arjun Valiya Parambathu, Xinglin Wang +4

The mechanism behind the ${}^1$H NMR frequency dependence of $T_1$ and the viscosity dependence of $T_2$ for polydisperse polymers and bitumen remains elusive. We elucidate the matte…
