A 2D FT double-resonance imaging method for nuclei having a low gyromagnetic ratio is presented. The method is based on the twin-SEDOR pulse sequence that allows one to detect the signal only from the protons coupled to the rare nuclei by indirect interaction. The method was tested on boron-10-enriched Na2B12H11SH (BSH), in which the boron-10 played the role of the rare nucleus. The indirect imaging of the molecules containing boron-10 is obtained with a signal-to-noise ratio given by the coupled protons and with an effective suppression of the solvent signal. © 1995 Academic Press, Inc.

Abstract
A 2D FT double-resonance imaging method for nuclei having a low gyromagnetic ratio is presented. The method is based on the twin-SEDOR pulse sequence that allows one to detect the signal only from the protons coupled to the rare nuclei by indirect interaction. The method was tested on boron-10-enriched Na2B12H11SH (BSH), in which the boron-10 played the role of the rare nucleus. The indirect imaging of the molecules containing boron-10 is obtained with a signal-to-noise ratio given by the coupled protons and with an effective suppression of the solvent signal. © 1995 Academic Press, Inc.File in questo prodotto:
