PROCESS OF OBSERVATION OF SIGNALS OF QUADRUPOLE SPIN ECHO

摘要

radio spectrometry, study of structure of chemical compounds with use of nuclear quadruple resonance. SUBSTANCE: process involves action on sample carrying quadrupole nuclei with two radio frequency pulses with time interval tau between them and basic frequency ωQ+DELTAωQ of one of pulses and basic frequency ωQ-DELTAωQ of the other pulse, where ωQ is resonance frequency of excited junction; DELTAωQ is amount off-resonance within limits of half-width of observed line of nuclear quadrupole resonance. Signals of spin echo are recorded on resonance frequency. EFFECT: generation of additional information on structure of chemical compounds thanks to observation of signals of echo of wide lines of nuclear quadruple resonance. 2 dwg
