Nuclear magnetic resonance (NMR) relaxometry is a method that allows one to characterize the physical and dynamic properties of samples by analyzing nuclear-spin relaxation . Measurements of the longitudinal relaxation time T 1 , governing the restoration of thermal equilibrium in a sample (corresponding to the growth of static magnetization in high-field NMR), and the transverse relaxation time T 2 (determining the decay of oscillating transverse magnetization) provide valuable information about sample environment. In contrast to NMR spectroscopy, relaxometry can be performed with cheaper lower-field magnets as generally there is no need to obtain a well-resolved NMR spectrum . This approach has been used in agricultural , petrochemical , and food sciences, as well as in the analysis of biological samples .
