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 editing.
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 Mathematica.

ASTM - High-resolution
solution-state 13C NMR
Figure 3. 13C test
spectrum of ASTM, one scan, 7 Tesla, 75 MHz, ppm scale. Processed
using Mathematica.

Cross-Polarization - 13C
NMR Adamantane with proton decoupling
|
| Figure 4. 13C Adamantane
Cross-Polarization Test Spectrum. 1 scan, 1 msec cross
polarization CPMAS with proton decoupling . Magnetic field
strength - 7 Tesla, 75 MHz, ppm scale. Processed using
Mathematica. |
13C high-resolution solid-state NMR under MAS -
Anisic acid
| Figure 5. Anisic acid, 128
scans 1 msec CPMAS with proton decoupling, 13C
high-resolution solid-state NMR. |
