Abstract

We have observed the 1-bond ¹⁹⁹Hg-¹⁵N J-coupling (¹J(¹⁹⁹Hg,¹⁵N) = 1050 Hz) within the Hg^II-mediated thymine-thymine base pair (T-Hg^II-T). This strikingly large ¹J(¹⁹⁹Hg,¹⁵N) is the first one for canonical sp²-nitrogen atoms, which can be a sensitive structure-probe of N-mercurated compounds and a direct evidence for N-mercuration.
