DMS dispersion plots of molecule set C3. Measurements were recorded in an N2 environment seeded with methanol vapor (1.5% mole ratio) at T = 150 °C, T = 225 °C, and T = 300 °C. The dispersion data of C3a are plotted in black and that of C3b is plotted in red. Molecule C3a exhibits an IMHB (highlighted in green), whereas molecule C3b does not. Protonation sites, as determined by DFT calculations, are highlighted in red. Errors are calculated as in Fig. 1, but are omitted for clarity
