... Optical properties of glassy SiS 2 and the 21 micron feature. ... Optical constants: . glassy SiS 2 Some details: . SiS 2 was prepared as a bulk glass and as single crystal by quenching of the molten sample and by a vapor transport method, respectively. ... Both the reflection and transmission measurements were performed in the wavenumber range from 20 to 5000 cm -1 . ...

... A laboratory approach to the interstellar sulfide problem. ... Optical constants: . ... The sulfides were synthesized from the native elements by the evacuated silica tube method with an annealing at 1273 K. The resulting sulfide powders were portioned, pressed to pellets, and melted in an arc furnace. The molten samples were quenched. For samples with x=0.0, 0.1, 0.25, 0.4, 0.5, 0.6, 0.75, 0.9, reflectance by polished surfaces was measured in the range from 2 to 500 microns. ...
... Aluminum oxide and the opacity of oxygen-rich circumstellar dust in the 12-17 micron range. ... Optical constants: . amorphous alumina (compact/porous) Some details: . ... The optical constants directly obtained from the data by Lorentz oscilator fitting for the range 20-1300 cm -1 correspond to porous alumina. Assiming that the pores are filled with liquid water the optical constants for "compact" alumina were derived using the Bruggeman rule of effective medium theory. ...

The nanodiamonds were extracted from Murchison meteorite material using the procedures similar to those employed by Tang and Anders (1988, Geochim. ... Acta, 52, 1235). The mass absorption coefficient in the range from 0.2 to 500 micron was derived from the transmission spectra of the diamonds in KBr and polyethylene pellets for T = 10 and 300 K.

... Optical characteristics of amorphous SiO 2 in the region 1400-200 cm -1 . ... Optical constants: . amorphous SiO 2 Some details: . Reflectance of polarized radiation at the incidence angle 12 deg was measured in the range from 1400 to 200 cm -1 for several samples of amorphous SiO 2 . Special technique applied allowed to reduce the relative errors downto 1% for the reflectance values of 0.005-0.8. The optical constants were obtained by the Kramers-Kronig method. ...
