Partial least squares regression (PLSR) models have also been developed to predict oil viscosity from transverse relaxation time (T2) distributions and diffusion coefficients estimated from NMR 4.

To that end, researchers have discovered that nuclear magnetic resonance (NMR) can be a powerful tool ... “The transverse relaxation time (T 2) measurement has been accepted as a rapid method ...

NMR relaxation ... the time it takes for the moments to "relax" back to equilibrium. Because relaxation times differ depending on the molecule and its environment, the information gathered by NMR, ...
