15.4: Spectral Characteristics of the Benzene Ring
For the 1 H NMR spectrum of p-bromotoluene, the absorption for the benzylic protons appears as a strong singlet at 2.28 ppm. Due to the molecule's symmetry, the aryl protons appear as two …
6.3: IR Spectrum and Characteristic Absorption Bands
2021年12月16日 · The C=C stretching of an alkene only shows one band at ~1600 cm-1 (Figure 6.4b), while a benzene ring is indicated by two sharp absorption bands, one at ~1600 cm-1 …
