1D NMR spectra extracted from the DOSY data of sample B in D₂O at 40 °C. The spectra were acquired at the first gradient step, G₁. The DOSY experiments were performed using the GR probe (previous study, Run 1) (a) and the Diff BBI probe (present study, Run 2) (b). See Table 2 for the parameters of these experiments
