The frequency offset effects of NQR of spin I = 1 for remote detection

Abstract

The frequency offset effects of the signal interference during steady-state pulse sequences for remote nuclear quadrupole resonance (NQR) of 14N nuclei were investigated for the purposes of optimization in remote NQR. The experimental investigations with the separation of interfering NQR signals in sequences for observing signals {α0°|β90°-τ-α180°|β90° - τ} and {α0° |β90° - τ- α0° |β270° - τ} were carried out. The applications of the spherical tensor method for pure NQR of spin I = 1 for the investigation of these sequences and one pulse sequence, two pulse sequences are presented, too.
