The chemical shifts were read and arepresented in Table 1.Except where indicated, thecoupling constants, and therefore the peak shapes, areessentially solvent-independent and are presented onlyonce.For D2O as a solvent, the accepted reference peak (δ) 0) is the methyl signal ofthe sodium salt...

Hence, PURGE solvent suppression remains a viable solvent suppression technique in the OneNMR Probe. Figure 6. Deuterium signal-to-noise measurement for the OneNMR Probe as measured on CDCl3. At a value of greater than 7200-to-1, this spectrum demonstrates performance that is more than double...
