Toluene nmr. chem. 6a), we can see that there are three signals. edu/jmol/nmr/toluene. <IMAGE> (a) How many different kinds of protons are there in toluene? (b) Explain why the aromatic region around d7. For example, 4. The data is related to a study on cation exchange in pseudorotaxanes published A precise analysis of the 'H nmr spectrum of toluene as a dilute solution in carbon disulfide yields a revised set of spectral parameters. Some say there are two signals while Find the proton chemical shifts of toluene and other compounds in different solvents, such as toluene-d8, acetone, ethanol, and water.
