| Abstract: | The absorption coefficient of liquid sulfur was measured in the energy range of 1.2–2.6 eV. No discontinuous behavior in the temperature dependence of the optical edge was observed at the polymerization temperature if the increase in light scattering occurring at the onset of the polymerization process is taken into account. Therefore, the electronic states that determine the optical edge appear to be insensitive to higher-order structural correlations. |
