Web1 Week 13 – 13 C NMR Spectroscopy Nuclear magnetic resonance (NMR) spectroscopy involves the molecules absorbing electromagnetic energy in the radiofrequency range. Two types of information are found in the 13 C – NMR spectra: 1. Number of carbons: Each unique carbon atom appears as a signal/peak. 2. Chemical Shift (d): The location of each … WebThe integration of the aromatic region is a potentially simple way to determine the number of substituents attached to the benzene ring simply by subtracting the number of aromatic H from 6, e.g. if you observe 4 aromatic H, then we must have 2 other substituents. This simple idea is often overlooked. A series of H-NMR spectra of simple ...
