Environmental NMR: Fast‐field‐cycling Relaxometry

摘要: Fast-field-cycling (FFC) NMR relaxometry deals with the variation of spin–lattice relaxation times (T1) in a complex system, as strength applied magnetic field is changed. Information about molecular dynamics can be achieved. Until now, only model theories for FFC have been developed polymer and material sciences. Just few applications performed environmental These mainly deal soil porosity, rock permeability, biomass transformations, natural organic matter dynamics. Further, also to monitor fate contaminants, understand nutrients at soil–plant interface, evaluate reaction mechanisms heterogeneous catalysis development green reactions. This article summarizes advances technique investigations describes tools used inorganic molecules compartments.
