We present the results of testing previously proposed method for identifying species archaeological wood materials by single-reflection attenuated total reflectance IR spectroscopy. The region 1270–1220 cm–1, in which two bands different intensities were found, is most promising samples. In spectra coniferous wood, a more intense band located at approximately 1265 and deciduous species, 1230 cm...

In this study, a new sorbent of chemically-modified activated carbon with L-arginine (AC-Arg) has been produced as solid-phase extraction, to trace Zn(II) and Cd(II) ions in real samples, including soil and water samples, by Flame Atomic Absorption Spectrometry (FAAS). Once the surface coverage value is determined, the surface modification has been investigated and assessed, while having em...

We have observed for the first time reflection spectra of an electric quadrupole transition for the cesium atom (6 (2)S(1/2)-5 (2)D(5/2)) line at an angle of incidence from theta(c)-11.9 to theta(c)+107.5 mrad, where theta(c) is the critical angle for total reflection. From a comparison with the calculated absorption in the attenuated total reflection, the oscillator strengths for s and p polar...
