FIELD: radio spectrometer, nuclear quadruple resonance, analysis of structure of chemical compounds. SUBSTANCE: method determining parameter of asymmetry of gradient of electric field in crystals containing quadrupole nuclei includes action with two-pulse train with time interval τ between pulses with repetition period To and basic frequency equal to resonance frequency of excited junction on sample, registration of signals of spin echo at time moment 2τ and determination of parameter η of asymmetry, reduction of repetition period To till maximum signal of additional echo is observed at time moment 3τ and determination of parameter of asymmetry with different time delays between pulses by ratio of amplitudes of additional echo to basic one in correspondence with given formula. EFFECT: determination of parameter of asymmetry under conditions of saturation of line of nuclear quadrupole resonance without use of magnetic field. 2 dwg
