Introduction to MQMAS NMR AIM: Optimization of the echo or antiecho amplitudes for either the shifted-echo or the split-t1 MQMAS sequences where the first pulse excites a p-quantum coherence only. The powder sample is in a rotor spinning at the magic angle. The multi-quantum magic-angle ...
摘要: Examines trinitrotoluene (TNT) absorption in soil and clays using [sup2]magic angle spinning (MAS) nuclear magnetic resonance (NMR) technique. Significance of using the technique; Features of the technique; Similarities between the result and binding samples....

The effects of storage methods and glycerol on the aging of breadcrumbs were studied using solid-state 13C CP/MAS NMR. After baking, a shift in C1 peaks from triplet (A-type) to singlet (V-type) was observed. Addition of glycerol reduced the carbon peak intensities of fresh and aged bre...
The local structure of P-rich and Se-rich phosphorus–selenium glasses was studied using high-resolution31P solid-state MAS NMR. Two-dimensional31P homonuclear through-bond correlation MAS experiments and 2D homonuclearJ-resolved MAS measurements were performed at high spinning frequency to probe P...
