A laboratory study to determine the effect of iron oxides on proton NMR measurements
Kristina Keating,Rosemary Knight +1 more
TL;DR: In this paper, the authors investigated the effect of the presence and mineralogic form of iron on measured proton nuclear magnetic resonance (NMR) relaxation rates and found that the presence of the iron oxides led to increases in the relaxation rates by increasing the surface relaxation rate.
