We report a simple two-dimensional NMR method for obtaining 2
H NMR pure-quadrupole spectra of
paramagnetic solids. This method is based on a quadrupole-echo sequence inserted with 180 pulses,
where the pulse spacings are incremented asymmetrically so that the 2
H magnetization evolves only
by the quadrupole interaction in the indirect dimension. It is shown that when the sequence is carried
out with strong radio-frequency pulses, the spectrum projected to the indirect dimension can be simulated
using the quadrupole-echo sequence without considering the effect of the paramagnetic shift.
The method was also used to investigate molecular dynamics by measurement and simulation of the
temperature dependence of the 2
H NMR spectra.
