In a preceding paper we determined the molecular contents of binary nuclei from homogeneous nucleation rate measurements studing ethanol-hexanol as a nearly ideal model system. Here we report the analogous measurements for the nonideal water-ethanol system known from previous investigations to display surface enrichment of ethanol in the nuclei. The nucleation pulse technique applied allows accurate measurements of homogeneous nucleation rates in the range 10(5)
