The NMR chemical shift differences (Δδ = δPT − δPT−free) among PT-free dsDNA, [Rp, Rp]-PT dsDNA and [Sp, Sp]-PT dsDNA.
(A) The chemical shift difference of protons in the bases between PT-free dsDNA and [Rp, Rp]-PT dsDNA, (B) The chemical shift difference of protons in the bases between PT-free dsDNA and [Sp, Sp]-PT dsDNA. (C) 31P chemical shift difference between PT-free dsDNA and [Rp, Rp]-PT dsDNA (black) and between PT-free dsDNA and [Sp, Sp]-PT dsDNA (red), respectively.
