The barrier to the ion-induced nucleation for water and methanol were calculated using a Monte Carlo method. The computer simulation confirms Wilson's findings in 1899 that anion is a better nucleator to produce water droplets than cation with the same magnitude of charge. The simulation also demonstrates that cation is a better nucleator to produce methanol droplets than anion. Structural and energetic analysis of prenucleation embryos offers a molecular insight into the sign preferences for hydrogen-bonding molecules in ion-induced nucleation.
