NMR relaxation.

A some what more indirect technique is to measure the decay times of the Nuclear Magnetic Resonance signals. This can provide approximate information on the diameter of the pores containing the liquid; more importantly it can provide information on the local environment of the liquid, on the internal surface morphology and on the surface wettability, all with optional spatial resolution.
