摘要：

We point out that the scaling law for onset vapor phase nucleation, lnS(onset) almost-equal-to 0.53[OMEGA(T(c)/T - 1)]3/2, with OMEGA = 1.77 (from CH3CN surface tension data) predicts the temperature dependence and approximate magnitude of CH3CN 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 OMEGA. We note that OMEGA, the excess molecular surface entropy/k, is more reliably extracted from the temperature derivative of the surface tension data.
