Abstract

The homogeneous nucleation rate of a supersaturated vapor of an aliphatic alcohol was measured in presence of a small concentration of the fluoroalcohol. The clustering produced from a supersonic expansion of water vapor containing a small concentration of the fluoroalcohol was compared with the water vapor containing aliphatic alcohol. The addition of fluoroalcohols at low concentration changed the composition of the condensation nuclei. A higher tendency to cluster water molecules was found in fluoroalcohols than in aliphatic alcohols.
