Homogeneous nucleation from the vapor phase has been a well-defined area of research for ∼120 yr. In this paper, we present an overview of the key experimental and theoretical developments that have made it possible to address some of the fundamental questions first delineated and investigated in C. T. R. Wilson’s pioneering paper of 1897 [C. T. R. Wilson, Philos. Trans. R. Soc., A 189, 265–307 (1897)]. We review the principles behind the standard experimental techniques currently used to measure isothermal nucleation rates, and discuss the molecular level information that can be extracted from these measurements. We then highlight recent approaches that interrogate the vapor and intermediate clusters leading to particle formation, more directly.

“…Pressure-time histories without and with condensation , respectively, appear like the p(x) graphs in Fig. 4.1 (Wegener 1975, Barschdorff 1975. At a given observation station,a pressure rise with respect to the ideal isentropic expansion and/or a light scattering signal reveal the onset of condensation and the history of the corresponding particle path ( Fi g. 2.2) can be computed as shown in Section 2.…”

“…Heat addition exceeding the value of ~~~~ may caus e T 38 shock waves or unsteady flows to occur (e. g. Wegener 1975) , and these phenomena invalidate the simple treatment of Section 2. In this work ,we shall only be interested in diabatic flow where the heat addition does not lead to thermal choking or discontinuities in the flow .…”
