Extracting Proton Information from 13C NMR data

In addition to using chemical shift information to ascertain a carbon’s proton count (i.e. C, CH, CH2 or CH3), 13C NMR experiments can be set up in a variety of ways to assist with this process.


The following simulated spectra compare a variety of 13C NMR experiments for aspartame. Please note that there are variations to the list below that are not being shown. These include such experiments as DEPTQ-135 and DEPT-HSQCSE (sensitivity enhanced).
