Sample NMR Spectra obtained with SpinCore RadioProcessor
| This page presents some
representative high-resolution solid-state MAS NMR
spectra obtained by Dr. Tom Pratum of Western
Washington University at 7 Tesla using SpinCore
RadioProcessor boards. Spectra and their
descriptions are priovided as obtained, with minimum
2D PASS - Anisic Acid, 13C Solid-state
high-resolution MAS NMR
|Figure 1. 2D
plot from a 2D PASS experiment (13C
MAS sideband separation). Sample: anisic
acid. Cogwheel phase cycling, 11
phases in 360/11 increments, ran as separate
experiments but written to the same file,
appending the data for each increment.
Data processed with nmrPipe.
Ni2P - 31P NMR in the solid
state under MAS
|Figure 2. 31P
spectrum of Ni2P spinning at about 3
kHz (1000 scans, the baseline has not been
corrected for in any way). This might be
interesting since the spectral width needs to be
very large to obtain this (this spectrum covers
over 400 kHz). Processed using
ASTM - High-resolution
solution-state 13C NMR
