Proton Transfer Equilibria and Critical Behavior of H-Bonding

Figure 3

Proton transfer degree from NQR measurements for complexes composed of chlorine containing proton donors plotted versus Δ𝑝𝐾_𝑁: (1) CCl₃COOH complexes (𝜉=0.12), (2) CHCl₂COOH complexes (𝜉=0.42), and (3) C₆Cl₅OH complexes (𝜉=0.74) [20].
