The suppression of synchronous interference NQR
with Zeeman modulation

Politanskii L. F., Sa­mi­la A. P., Khandozhko V. .

Keywords: NQR, Zeeman modulation, synchronous interference, hexamethylenetetramine.

The principles of frequency and Zeeman modulation in nuclear quadrupole resonance were considered, and the advantages of the latter were shown. The authors propose a method to eliminate the synchronous noise caused by switching of the magnetic field. Results of observations of the resonance line with 14N in the hexamethylenetetramine sample weighing 2 g were given.
