WebCounterions are important constituents for the structure and function of nucleic acids. Using 7 Li and 133 Cs nuclear magnetic resonance (NMR) spectroscopy, we investigated how ionic radii affect the behavior of counterions around DNA through diffusion measurements of Li + and Cs + ions around a 15-bp DNA duplex. Together with our previous data on 23 Na + … Web1 H NMR (300 MHz, DMSO): 1 H NMR (300 MHz, DMSO) δ=8.69 (s, 1H, H ...
