Resumen:
We study the evolution of the FID in a system where the Hamiltonian is not motionally averaged (in the observation time scale, namely the FID time) and exhibits other non-magnetics states, such as liquid crystal mesophases (LC). We found: overlapping of coherence signals (Liouville equation for the spin states, close magnetic system ) and decay induced by adiabatic quantum decoherence.The adiabatic quantum decoherence is also present in the evolution of the magnetics observables toward state of quasiequilibrium, as occur after the preparetion pulses of the Jeener-Broekaert sequence.
