Interesting results were obtained in the initial investigation of the nucleation behavior of supersaturated sulfur vapor up to temperatures above the transition. This is a second-order phase transition in liquid sulfur characterized by a change in molecular structure from closed sulfur rings to open radical chains within a narrow temperature range. Although the temperature dependence of the constant rate supersaturation is not correctly represented, it is surprising again how well classical nucleation theory describes experimental results even for such a complex substance. For homogeneous nucleation, there are indications that the gimel transition influences the nucleation behavior as a consequence of the changing thermophysical properties - density and surface tension - of the liquid sulfur. Photoinduced nucleation shows a striking effect directly correlated with the transition. Below the gimel temperature, the vapor is extremely sensitive to irradiation with light in the range 260-360 nm that decreases the constant rate supersaturation by about a factor of 10. At the transition temperature, the photo effect vanishes sharply. The close correlation of the structure of liquid sulfur and the nucleation behavior is interpreted as a confirmation of the capillarity approximation that indeed the properties of the liquid determine nucleation behavior.
