b-2-deoxyribose ring coupling constants

β-2-deoxyribose (2-deoxy-erythro-pentose)

Here is a collection of correlations between carbon-proton coupling constants and pseudorotation angle (P) in unsubsituted β-2-deoxy-ribose, i.e. without base or phosphate. With some caution these couplings can be used as approximations for the corresponding coupling constants in nucleosides/nucleotides.
To calculate the coupling constant just enter the pseudorotation angle (P) in degrees. In some cases the relative amount of the two dominant C4'-C5' rotamers (gg and gt) is required. In nucleic acids gg is the sole rotamer present.

Pseudorotation angle (P) = °, gg rotamer = %
