Further, the direct measurement of J-couplings is obscured in solid-state samples due to the dipolar and chemical shift anisotropy (CSA)-dominated line broadening, even under the magic angle spinning (MAS). We present a new multiple frequency selective spin-echo method based on Hadamard matrix ...
Solid state NMR is widely applied in studies of solid state chemistries for hydrogen storage reactions. Use of 11B MAS NMR in studies of metal borohydrides (BH4) is mainly focused, revisiting the issue of dodecaborane formation and observation of 11B{1H} Nuclear Overhauser Effect....
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 ...
