¹H pulsed NMR is a technique for measuring spin-spin relaxation（transverse relaxation）and spin-lattice relaxation（longitudinal relaxation）. Analysis of transverse relaxation decay using Weibull function provides the time constant（spin-spin relaxation time; T₂）and shape parameter（Weibull coefficient; W）. The T₂ and W value correlate with molecular mobility and its distribution, respectively. When the material is composed of multiple components, decay of the total is observed as a superposition decay of each component. The fraction（F）of each T₂ component is proportional to the signal intensity of each component. By using three parameters（T₂, F, and W）, It is possible to know quantitative the crosslinking density and inhomogeneity of the soft materials.
