A study of transverse relaxation of 87Rb in agarose gels by triple-quantum filtration

The use of 87Rb NMR for measuring the transmembrane K + flux in living tissues has been investigated. 87Rb + is a spin- 3 2 , quadrupolar nucleus, and is thus subject to rapid, biexponential relaxation. The transverse relaxation of 87Rb + in agarose gels was examined by triple-quantum filtration, an...

Summary:The use of 87Rb NMR for measuring the transmembrane K + flux in living tissues has been investigated. 87Rb + is a spin- 3 2 , quadrupolar nucleus, and is thus subject to rapid, biexponential relaxation. The transverse relaxation of 87Rb + in agarose gels was examined by triple-quantum filtration, and the results of these studies were used to interpret the observed NMR visibility of 87Rb + in biological tissues.
