Web1), and near-IR spectrum (4000-13000 cm-1). The mid-IR spectrum is the most widely used in the sample analysis, but far- and near-IR spectrum also contribute in providing information about the samples analyzed. This study focused on the analysis of FTIR in the mid-IR spectrum. The mid-IR spectrum is divided into four regions: Webthe IR vibrations of the surface metal oxide species in the 1000 cm- 1 region because of strong absorp- tion by the oxide supports below 1000 cm -1, but the overtone region at 2000 cm- 1 is always observ- able. The in situ IR spectra of a series of titania supported rhenium oxide catalysts are presented WebAlkynes have characteristic IR absorbance peaks in the range of 2100-2250 cm-1 due to stretching of the carbon-carbon triple bond, and terminal alkenes can be identified by … sign batch file
