Abstract

Experimental and theoretical study of quasistationary and stationary states that are established in the quadrupolar spin system subjected to the steady-state sequences which consist of a chain of identical pulses and can be preceded by a preparatory pulse. We have obtained theoretical expressions for the magnetisation of the spin system that take into account off-resonance conditions during the effect of the pulses. Frequency dependencies of the NQR signal in the quasistationary and stationary states are shown for C3H6N6O6 (RDX) and NaNO2, and compared with theoretical results.
