Abstract
THE effect of certain monolayers in reducing evaporation of liquids has led to much speculation about the mechanism and the reasons for differences in effectiveness between different monolayers1. The effect has usually been attributed either to an alteration in the accommodation coefficient of water or to an activation energy barrier to diffusion through the monolayer2. Mass transfer across interfaces is usually governed by molecular diffusion through a stagnant fluid layer next to the interface3 and the rate ν often obeys the simple equation 
where D is the diffusion coefficient of the transferring substance, x is the thickness of the diffusion layer, and C0 and C are the concentrations at the two surfaces of the diffusion layer.
