WebFigure 2. Group frequency and fingerprint regions of the mid-infrared spectrum. The region of the infrared spectrum from 1200 to 700 cm -1 is called the fingerprint region. This region is notable for the large number … WebFTIR spectra for the deposited films also showed a large amount of OH groups in the films at around of 2500cm-1. If annealing technique applies, these peaks will be decrease. As whole by comparing the Fig. 3 with Table 3 it is clear that increasing the working pressure decreases the impurity contents in sample B. Fig. 3 shows
