Kirshenbaum, A.G. Streng Title: Molar extinction coefficients of liquid O3F2, O2F2, and O3 in the visible range Journal/Source: J. Chem. Phys., 35, 1440-1442, (1961); http://link.aip.org/link/doi/10.1063/1.1732063 Data: table, diagram Energy/Wavelength range: 200 - 480 nm Resolution: Temperature: 77 K Temperature dependence: yes Pressure/Concentration: Phase: liquid pH: Comments: The absorption spectra for solutions of liquid O3F2, O2F2, and O3 in a Freon mixture of CClF3 and CCl2F2, and that of liquid O3 in liquid O2 were measured at 77°K and their molar extinction coefficients calculated. The effect of temperature on the molar extinction coefficient of liquid O2F2 in the Freon mix was studied. Author to whom correspondence should be addressed: (e-mail address):
