Diffusion coefficient of 1-undecanesulfonic acid sodium salt in dideuterium oxide

Abstract

This chapter provides the diffusion coefficient of 1-undecanesulfonic acid sodium salt in dideuterium oxide at different concentrations measured using NMR spin echo pulse gradient.

These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
