METHOD FOR DETERMINING WIDTH OF OBSERVED NUCLEAR QUADRUPOLE RESONANCE LINE Russian patent published in 1997 - IPC

Abstract RU 2086966 C1

FIELD: physical methods in chemistry. SUBSTANCE: method includes periodically affecting substance containing quadrupole nuclei with two radio-frequency pulses with time interval τ and filling frequency equal to that of excited transfer; measuring optimal conditions for excitement and registering spin echo signal; measuring time T*2

from the latter and determining line width from formula Δν = 1/2πT*2

. Duration of one or two pulses is measured, and double- humped signal shape is registered, its maxima allowing measuring time T*2

. EFFECT: improved procedure. 4 cl, 5 dwg
