In NMR, nuclear magnetic moments are used to measure specific physical and chemical properties of materials.
The relaxation rate depends strongly on the mobility (fluctuations, diffusion) of the microscopic environment and the strength of the applied magnetic field.
Key Materials science properties are often described in different fields using the terms mobility / dynamics / stiffness / viscosity / rigidity of the sample.
These properties are usually dependent on atomic and molecular motion in the sample, which may be measured using time-domain NMR and fast field cycling relaxometry.
This helps to save time and resources and makes it possible to use an NMR relaxometer as a portable express analyzer in different branches of industry, science and technology, environmental protection, etc.
