Theoretical study of spin-spin coupling across the hydrogen (O-H⋯N) bond in adenosine derivatives
2009
The study of spin-spin coupling constants across hydrogen bond provides useful information about configuration of complexes. The interesting case of such interactions was observed as a coupling across an intramolecular hydrogen bond in 8-bromo-2′,3′-O-isopropylideneadenosine between the -CH2OH (at 5″ proton) group and the nitrogen atom of adenine. In this paper we report theoretical investigations on the 4h J NH coupling across the H″-C-O-H···N hydrogen bond in adenosine derivatives in various solvent models.
