Pore size distribution from hydrogen and sodium NMR using the transverse relaxation at 4.7 T

Restricted diffusion and exchange of water in porous media: Average structure determination and size distribution resolved from the effect of local field gradients on the proton NMR spectrum

“…Consequently, the diffusion curve built by taking the total spectrum area is the sum of the different contributions of pores of different sizes. A similar situation occurs for relaxation data, especially T 2 measurements, for which multi-component analysis or Inverse Laplace Transformation (ILT) are well established methods to access the size distribution of pores in different materials [13,14]. More recently, the use of the ILT has been extended in 2 and 3 dimensions producing T 1 /T 2 /D correlation and exchange data.…”
