FIELD: radio spectroscopy, analysis of chemical compounds. SUBSTANCE: method includes action on sample with two radio frequency pulses with time interval τ between them, with carrier frequency equal to frequency of excited junction, with repetition period To of pulse sequence, recording of signals of echo by which width of line of nuclear quadrupole resonance ( NQR ) is measured. Repetition period To is being decreased till maximum signal of additional echo is observed at time moment 3τ and values of magnetic and electric fields are separated and determined by forms of basic and additional echoes. EFFECT: possibility of separation and determination of contributions caused by electric and magnetic interaction to width of line of NQR. 1 dwg
