 Title    Nachweis von Se6, Se7 und Se8 in Lösungen yon Selen mittels Hochdruckflüssigkeitschromatographie Detection, of See, Se7 and Ses in Selenium Solutions by High-Pressure Liquid Chromatography  
 Abstract    Dissolution of crystalline Ses or extraction of glassy or red amorphous selenium, prepared from aqueous Se02 by reduction, by organic solvents yields solutions containing Se6, Se7 and Ses in equilibrium as shown by HPLC. The equilibrium explains the concen-tration 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 See, Se7 and Ses, 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.
