Two-frequency saturation in pulsed NQR of14N

Soviet Physics Journal Aims and scope

Abstract

The potentialities of variation of the signal/noise ratio in pulsed NQR for spin I=1 with saturation of the quadrupole system at an adjacent transition are examined. A method is proposed for correlating the lines in the14N NQR spectra at the frequencies ν+ and ν−. Calculations are carried out for the two limiting cases by the kinetic-equation and density-matrix method. The experiment was performed with14N nuclei in sodium nitrite (NaNO2) at 77 K.
