A new approach to determination of micropore size by Xe-129 NMR spectroscopy
Based on confined one-dimensional collision model, we find that the coefficient delta(Xe-Xe) arising from Xe-Xe collisions measured by 129 Xe NMR experiment is related to the pore size (D = 1.681delta(Xe-Xe)(1/2)) indicating a new approach to the determination of the size of narrow channels or pores in various microporous materials.
