Fig. 4. 1H NMR spectra of Aβ16 (black curve) with 1 equivalent of Cu(i) (grey curve) and 1H NMR spectra of H6A–H14A (dark blue curve) with 1 equivalent of Cu(i) (light blue curve) at pH 7.3. The chemical shifts of protons observed with the addition of Cu(i) are indicated with dotted lines. All chemical shifts were calculated relative to the internal TSP reference at 0.00 ppm.
