The case of excitation of nuclear quadrupole resonance (NQR) in nitrogen-containing compounds is examined for significant sample removal under conditions of strong dispersion of the registered signal. Principal limitations on the sensitivity of remote NQR observations are demonstrated. A method of registering resonant lines after fading of the main signal is suggested.
