Effects of radial radio-frequency field inhomogeneity on MAS solid-state NMR experiments [PDF]
Magnetic Resonance, 2021 Radio-frequency field inhomogeneity is one of the most common imperfections in NMR experiments. They can lead to imperfect flip angles of applied radio-frequency (rf) pulses or to a mismatch of resonance conditions, resulting in artefacts or degraded ...

Solid-State NMR Study of New Copolymers as Solid Polymer Electrolytes
Magnetochemistry, 2018 We report the analysis of comb-like polymers by solid-state NMR. The polymers were previously evaluated as solid-polymer-electrolytes (SPE) for lithium-polymer-metal batteries that have suitable ionic conductivity at 60 °C.

Pseudo-resonance structures in chiral alcohols and amines and their possible aggregation states
Frontiers in Chemistry, 2022 We now report that some chiral compounds, like alcohols, which are not sterically hindered atropisomers nor epimer mixtures, exhibit two sets of simultaneous NMR spectra in CDCl3.

Solid‐state NMR Structure Determination [PDF]
IUBMB Life, 2003 AbstractBiological applications of solid‐state NMR (SS‐NMR) have been predominantly in the area of model membrane systems. Increasingly the focus has been membrane peptides and proteins. SS‐NMR is able to provide information about how the peptides or proteins interact with the lipids or other peptides/proteins in the membrane, their effect on the ...
