The expanded H1–H8/H2/H6 and H1–H1 regions of the exchangeable proton 2D JR-NOESY spectrum of Tel26 in K⁺ solution at 1°C. NOEs are labeled as follows: intra-tetrad NOEs are labeled in red, sequential NOEs are labeled in green, inter-tetrad NOEs are labeled in blue, NOEs between stacking adenine H2 protons and G-tetrad imino protons are labeled in black. Conditions: 1°C, 25 mM K-PO₄, 70 mM KCl, pH 7.0, 2.5 mM DNA.
