Calculating p$$K_a$$(H$$_2$$O) and p$$K_a$$(D$$_2$$O) using path integral molecular dynamics

Thomsen, B.; Shiga, Motoyuki

We present the p$$K_a$$ of water and phenol in bulk and water solution respectively calculated using path integral molecular dynamics (PIMD) and ab-initio molecular dynamics (AIMD). The PIMD method offers the advantage of modeling the quantum effect of the protons, thereby offering a larger accuracy over the AIMD. Furthermore we study the results of isotope exchange from hydrogen to deuterium in the two systems, and effect not captured by AIMD.
