Sentence examples for carbon assignment from inspiring English sources

A proton to carbon assignment could be achieved by an HSQC experiment.

During the verification process, the program checks whether or not the carbon atom assignments correspond to the experimental chemical shift correlations comprising the skeletal atoms making up the fragment.

Along with the chemical shifts of the remaining carbons, the assignment of all the NMR signals is summarized in Table 1 and Figure 2(a).
