Abstract
A new two-step quench technique has been used to decouple the effects of nucleation and growth in studies of homogeneous nucleation in the system (isobutyric acid) + water in the neighborhood of the upper critical solution temperature. The results demonstrate that the nucleation process is normal, in accord with theories that ascribe anomalous behavior of the cloud-point curve to critical slowing down of the growth of droplets.
