Abstract: | A method of obtaining high polarization and pure spin states of impurity nuclei with a moderately strong quadrupole interaction
in solid diamagnetic hosts whose nuclei have spin 1/2, a large g factor (like 1H and 19F), and a high degree of polarization is proposed. The method employs cross-relaxation transitions of the impurity nuclei
with the host spins (with adiabatic variation of the external magnetic field) and simple radio-frequency pulses that invert
the host nuclei or give rise to two-spin resonance of the host and impurity nuclei.
