Infrared and Raman spectra have been recorded for room-temperature-phase, powdered samples of LiNO,, NaNO,, KNO,, RbNO,, CsNO,, AgNO,, and TINO,. For the trigonal systems, the nitrate pairs LiNO,, NaNO, and RbNO,, CsNO, give almost identical spectra. For the orthorhombic systems, AgNO, and TINO, give similar spectra, whereas that of KNO, is significantly different. Site and correlation field perturbations are considerably more pronounced in the antisymmetric stretching region (v, ca. 1400 cm-') than in the antisymmetric bending region (v4 ca. 700 cm-I). Although lifting of the degeneracy of E' modes was frequently observed, the reported split of the v4(E1) mode (ca. 716 cm-I) of the aragonite form of KNO, could not be confirmed. Multiple internal reflectance techniques have been employed to observe the extremely intense v,(E') infrared fundamental ca. 1400 cm-'.

“…This effect can suggest that even in flowing N 2 , the content of oxygen, related to its presence on the composite surface in the form of adsorbed and deposited species, is enough to combust entirely the polymer film. Figure 2 shows that the process of PFA oxidation occurs in the temperature range of 290-590°C with the maximum at about 500°C, which corresponds to the CO 2 emission manifested by the appearance of two IR bands observed at 2310 and 2350 cm -1 [47]. This finding obviously shows that the PFA film is very temperature-sensitive, and only lowtemperature activation (below 290°C) can protect it against any significant damage.…”

The mechanism of thermal degradation of poly(furfuryl alcohol) (PFA) deposited on the MCM-48 mesoporous silica was studied. The behaviour of the thin PFA film homogeneously dispersed on the silica surface (the material with the real PFA/MCM-48 mass ratio of 0.06) was compared to that of the 3D structure of PFA completely filling the MCM-48 channels (the material with the real PFA/MCM-48 mass ratio of 1.02). The progress of decomposition was controlled by thermogravimetry accompanied by infrared spectroscopy providing information on the composition of gaseous products evolved during the sample degradation. The thermal treatment of PFA/ MCM-48 composites at various temperatures in the range of 523-1323 K enabled us to synthesize two series of PFAderived carbon adsorbents: (1) containing the degraded PFA film supported on the mesoporous silica and (2) CMK-1 type carbon replicas, which were obtained by leaching of SiO 2 from the PFA/MCM-48 composite after the previous pyrolysis. The structural and textural properties of these materials were determined by powder X-ray diffraction, DRIFT spectroscopy and low-temperature nitrogen adsorption. Furthermore, the samples were tested as adsorbents of different volatile organic compounds (VOCs). The PFA/MCM-48 materials showed the high adsorption capacity only in the removal of polar molecules, whereas CMK-1 was effective in the elimination of linear alkanes and aromatic VOCs as well.

“…The atmosphere of Mars has a composition that is 95% CO 2 (Owen et al, 1977), which produces several absorption bands in the near-infrared region (1.0-4.0 mm) (Martin and Barker, 1932).…”

a b s t r a c tThe observations of Mars by the CRISM and OMEGA hyperspectral imaging spectrometers require correction for photometric, atmospheric and thermal effects prior to the interpretation of possible mineralogical features in the spectra. Here, we report on a simple, yet non-trivial, adaptation to the commonly-used volcano-scan correction technique for atmospheric CO 2 , which allows for the improved detection of minerals with intrinsic absorption bands at wavelengths between 1.9 and 2.1 mm. This volcano-scan technique removes the absorption bands of CO 2 by ensuring that the Lambert albedo is the same at two wavelengths: 1.890 and 2.011 mm, with the first wavelength outside the CO 2 gas bands and the second wavelength deep inside the CO 2 gas bands. Our adaptation to the volcano-scan technique moves the first wavelength from 1.890 mm to be instead within the gas bands at 1.980 mm, and for CRISM data, our adaptation shifts the second wavelength slightly, to 2.007 mm. We also report on our efforts to account for a slight $0.001 mm shift in wavelengths due to thermal effects in the CRISM instrument.
