The 1H-NMR spectra (imino and aromatic regions) of G-quadruplexes M0–M7 recorded in Na+ containing conditions at 25°C. The blue dotted lines follow some among the resonances with the greatest chemical shift changes. Additional NMR signals from minor species present in some of the samples are marked with asterisks.
