WebFTIR spectroscopy in particular is of great interest due to the chemical information directly accessible and its high specificity in the fingerprint region (<1500 cm −1) [15,16]. It has already proven useful for the characterization of sol-gel based processes [17,18,19]. Attenuated total reflection probes (ATR) allow in-line measurements even ... Webare seen in the FTIR spectra which were shown in Ta-ble 3, as it is observed from the spectra these are too smaller than the main pick. Peaks in the spectral range at around of 1600 cm-1and 2300 cm-1 are attributed to vibrations of carbon impurity atoms in the film. The FTIR spectra for the deposited films also showed a
