资源简介：
Dynamic
nuclear polarization (DNP)-enhanced solid-state NMR spectroscopy
has been used to study an ionic liquid salt solution (N-methyl-N-propyl-pyrrolidinium bis(fluorosulfonyl)imide,
C3mpyrFSI, containing 1.0 m lithium bis(fluorosulfonyl)imide, 6LiFSI) in its glassy state at a temperature of 92 K. The incorporation
of a biradical to enable DNP signal enhancement allowed the proximities
of the lithium to the individual carbon sites on the pyrrolidinium
cation to be probed using a 13C–6Li REDOR
pulse sequence. Distributions in Li–C distances were extracted
and converted into a 3D map of the locations of the Li+ relative to the C3mpyr that shows remarkably good agreement
with a liquid-phase molecular dynamics simulation.
