Web1. Assign the peak values for the characteristic functional group bonds (C-Br, C-N, N=O, and aromatic C-C) from the IR spectra of your product. 2. Assign the characteristic protons from the 'H NMR spectra of your product. The 'H NMR spectra is (1) for pure ortho-product or (2) for pure para-product. WebMost organic functional groups absorb in the so-called “diagnostic region” of the spectrum at wavenumbers from 1500-4000 cm -1 and can be easily recognized. For example, carbonyl functional groups (C=O) typically show up around 1750 cm -1 and hydroxyl groups (O-H) stretches show up around 3500 cm -1 (see example spectrum below).
