J-modulated 19 F- and 1 H-detected dual-optimized inverted 1 J CC 1,n-ADEQUATE: A universal ADEQUATE experiment.

The recently reported 19 F-detected dual-optimized inverted 1 J CC 1,n-ADEQUATE experiment and the previously reported 1 H-detected version have been modified to incorporate J-modulation, making it feasible to acquire all 1,1- and 1,n-ADEQUATE correlations as well as 1 J CC and n J CC homonuclear scalar couplings in a single experiment. The experiments are demonstrated using N,N-dimethylamino-2,5,6-trifluoro-3,4-phthalonitrile and N,N-dimethylamino-3,4-phthalonitrile.
