HF acid ionization in water: the first step.
The results of a theoretical study of the first acid-ionization step to produce a contact-ion pair are presented for HF in water. The reaction is found to be an adiabatic quantum proton transfer, and has an activation barrier in a collective solvent reaction coordinate of ca. 3 kcal mol-1.
