Abstract

We point out that the scaling law for onset vapor phase nucleation, ln S _onset ≈ 0.53 [Ω( T _c / T -1)] ³² , with Ω = 1.77 (from CH ₃ CN surface tension data) predicts the temperature dependence and approximate magnitude of CH ₃ CN supersaturation ratio data, S . This is contrary to the conclusions of Wright, Caldwell and El-Shall who estimate too large a value (2.14) for Ω. We note that Ω, the excess molecular surface entropy/ k , is more reliably extracted from the temperature derivative of the surface tension data.
