The concentration of the fatty alcohol [functional form CnH(2n+1)OH] at the point of deflection in the evaporation rate was calculated from the particle size (Rdef). Assuming all molecules resided at the surface, a surface area per molecule was calculated (Amol).
Data for dodecanol data were recorded at 283 K, not 293 K, as explained in the text.
