The chemistry at the boundary between two interacting phases is a relatively new area, which is not well developed. Pioneering experiments by the Richmond group clearly show that at the interface between phases, the chemistry is remarkably different. We have examined these differences, and will report on insight from the fundamental molecular level into the adsorption process that governs the accommodation and uptake of atmospheric species at cloud/aerosol interfaces using combined ab-initio quantum mechanics (QM) calculations and molecular dynamics (MC) atomistic simulations. Hydrocarbons can act as important weather and air quality forcing agents, in particular in regions subject to urban traffic pollution.  The interaction of hydrocarbons and the air-water interface is essential to understanding how clouds or atmospheric aerosols influence air quality issues.
