dc.description.abstract	Dissolution of crystalline Se8 or extraction of glassy or red amorphous selenium, prepared from aqueous SeO2 by reduction, by organic solvents yields solutions containing Se6, Se7 and Se8 in equilibrium as shown by HPLC. The equilibrium explains the concentration dependence of the molar absorbance of such solutions observed earlier. Since the Raman spectrum of red amorphous selenium does not show any lines due to Se6 Se7 and Se8 a rapid interconversion of selenium molecules in solution at 20 °C is postulated. Red amorphous selenium may consist of a mixture of small and medium sized ring molecules.	en
