The 2D H_s(C_sN_bC_b)H_bH experiment has been proposed to achieve through-bond intranucleotide sugar-to-base correlations in ¹³C,¹⁵N-labeled nucleic acids.

Implementation on AVANCE spectrometers equipped with a third channel and gradient technology.

The original experiment was described in ( 93JACS11040 ).

In the H(CNC)H spectra, a conventional 2D 1H-1H map correlation is obtained only displaying sugar-to-base correlations starting from the anomeric sugar proton.
