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
WebNIST Technical Series Publications WebFourier transform infrared (FTIR) is the most commonly used form of infrared spectroscopy. When Infrared (IR) radiation passes through the sample, these infrared spectroscopies act on the principle. During the entire process, it absorbs some of the radiation. Experts record the radiation that passes through the sample.
