Variation in optical transmission and electrical resistance in a single sulfur liquid droplet during polymerization.
Electrical resistance and optical transmission anomalies are observed in a single droplet of liquid sulfur during polymerization and depolymerization from 155 degrees C to 190 degrees C. Correspondence is found with some of the effects observed in electrooptic studies on bulk samples. Unlike the bulk studies, however, the single droplet shows an optical transmission of laser light that appears to follow the viscosity curve in thermal dependence. This divergence between the two studies is interpreted in terms of scattering effects at the droplet surface.
