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 ). WebOther infrared-based techniques like FTIR/ATR or FTIR/DRIFT are specifically used to detect silicones adsorbed on a substrate (see Figure 1). However, in many cases, the layer of silicone on the top of the sample surface is so thin that only the fingerprint of the bulk of the sample is seen.
