NMR imaging of quadrupolar nuclei in liquid system has received less attention than the imaging of S = 1/2 nuclei due to difficulties associated with the quadrupolar interaction. The B-10 spatial distribution in (Na2B12H11SH)-B-10 in phantom has been obtained using an indirect J-coupling Double Resonance method. This procedure allows one to localize the quadrupolar nuclei by observing the protons J-coupled with them. The sensitivity gain in the indirect spatial localization of the B-10 nuclei with respect to to the direct one, is here computed and verified on the (Na2B12H11SH)-B-10 images.

Abstract
NMR imaging of quadrupolar nuclei in liquid system has received less attention than the imaging of S = 1/2 nuclei due to difficulties associated with the quadrupolar interaction. The B-10 spatial distribution in (Na2B12H11SH)-B-10 in phantom has been obtained using an indirect J-coupling Double Resonance method. This procedure allows one to localize the quadrupolar nuclei by observing the protons J-coupled with them. The sensitivity gain in the indirect spatial localization of the B-10 nuclei with respect to to the direct one, is here computed and verified on the (Na2B12H11SH)-B-10 images.File in questo prodotto:
