The application of submicro inverse-detection gradient (SMIDG) NMR probe technology at 600 MHz is demonstrated for the rapid acquisition of both 1 H-13 C and 1 H-15 N heteronuclear chemical shift correlation data. Using a 750 µg (ca 1.5 µmol, MW 505) sample of the complex spirononacyclic alkaloid cr
