Identifying Functional Groups from an IR Spectrum. The IR spectrum of an unknown compound is shown in Figure 12.28. What functional groups does the compound contain?
16 gru 2021 · The characteristic IR frequencies of stretching vibrations in Table 6.1 and Figure 6.3b provide very useful information to identify the presence of certain functional group, that can be generally summarized as:
The inside cover of the Wade textbook has a table of functional groups, and they are discussed in detail in ch. 2, pages 68 – 74 of the 6th edition. A table relating IR frequencies to specific covalent bonds can be found on p. 851 of your laboratory textbook.
