Structure of the Two-Dimensional NMR Relaxation Spectra of Porous Materials

Résumé

Two-dimensional NMR-relaxation spectroscopy, correlating various relaxation mechanisms, proved useful for studies dynamical processes that take place in various porous material [1-5]. Yet development of the Laplace-spectroscopy has been somewhat impeded by difficulties in creating a stable numerical multidimensional Laplace-inversion method free of faulty premises. Herein we shall discuss in terms of the eigenmodes theory a number of fundamental structural properties, viz. symmetries, overall intensities, signs and relative intensities of the diagonal and cross components, of the two-dimensional NMR relaxation spectra which could be used as constraints to design a stable and fast Laplaceinversion algorithm
