Some dynamical properties of nitrogen-14 quadrupolar spin-system with non-symmetric electric field gradient tensor

The behaviour of nuclear quadrupole resonance (NQR) signal was studied in the `observation windowsʹ between RF pulses after applying a multi-pulse sequence to a nitrogen-14 spin-system with a non-symmetric electric field gradient tensor using a phase-cycling technique. The experiments revealed some peculiarities in the behaviour of the signals which are important for the understanding of the dynamic properties of the quadrupolar spin-system.
