We have observed the 1-bond Hg-199-N-15 J-coupling ((1)J(Hg-199,N-15) = 1050 Hz) within the Hg-II-mediated thymine-thymine base pair (T-Hg-II-T). This strikingly large (1)J(Hg-199,N-15) is the first one for canonical sp(2)-nitrogen atoms, which can be a sensitive structure-probe of N-mercurated compounds and a direct evidence for N-mercuration.
