Abstract
Four-bond H8/H6-H1 scalar coupling correlations in two-dimensional correlated spectroscopy have been observed directly for the first time by using the J-scaled COSY [(1985) Chem. Phys. Lett. 116, 105-108] technique in a dinucleotide, cytidylyl(2'-5')guanosine (CpG). Unambiguous resonance assignment of nonexchangeable protons in CpG has been obtained using these H8/H6-H1' 4-bond correlations and the various 3- and 4-bond sugar ring proton correlations observed in the COSY and SUPER COSY experiments.
