WebNov 9, 2024 · IR spectra can be divided into two main regions: Diagnostic region – generally has fewer peaks and provides the clearest information. This region contains all signals that arise from all bonds in a molecule. Fingerprint region – contains signals resulting from the vibrational excitation of most single bonds ( stretching and bending ). WebFTIR Spectroscopy, Fourier-transform infrared spectroscopy, is concerned with the vibration of molecules. Each functional group has its own discrete vibrational energy which can be used to identify a molecule through the combination of all of the functional groups. This makes FTIR microscopy ideal for sample ID, multilayer film characterization ...
