Using DEPT to Count Hydrogens

You have probably noticed another characteristic of NMR spectra—all of the peaks are 

The lack of splitting due to coupling is easy to understand. NMR spec- 

Splitting due to coupling is absent for a different reason, one that has to do 

What we gain from broadband decoupling in terms of a simple-looking spectrum comes at the expense of some useful information. For example, being able to see splitting corresponding to one-bond coupling would immediately tell us the number of

In summary, considerable information is available from a l3C-NMR spectrum. First, the number of different carbons can be counted, providing information about the symmetry of the molecule. Second, the chemical environment of the carbons can be deduced from their chemical shifts. Third, information from the DEPT spectra tells how many hydrogens are bonded to each carbon. Some of this same information is provided by the ll-NMR spectrum. However, the two types of spectra often provide complementary information and help solidify deductions made with one alone. 13C-NMR is especially useful when the H-NMR spectrum is too complex for ready interpretation.
