What is the interpretation of the IR spectrum?
The interpretation of infrared spectra involves the correlation of absorption bands in the spectrum of an unknown compound with the known absorption frequencies for types of bonds.How do you identify functional groups in IR spectrum?
The normal way to approach interpretation of an IR spectrum is to examine the functional group region to determine which groups might be present, then to note any unusually strong bands or particularly prominent patterns in the fingerprint region.How to Read FTIR Analysis Results Graphs
