BULBED CAPILLARY EXTERNAL REFERENCING METHOD USING A SUPERCONDUCTING MAGNET NMR INSTRUMENT

Whether the bulbed capillary external referencing method developed with an electromagnet NMR instrument can be performed also with a superconducting magnet instrument by only changing g(cy) from 2pi/3 to 0 is studied. As the result, the same bulbed capillary and procedures giving high precisions and accuracies are found to be applicable to either electromagnet or superconducting magnet instrument and to either H-1 or even C-13 spectra. Thus, the validity of the generalized bulbed capillary theories and the superiorities of the bulbed capillary method over previous referencing methods are made clear.
