Interpreting Carbon NMR data requires analyzing chemical shifts, signal multiplicity, and integration patterns to identify different carbon environments within a molecule. The DEPT experiment further classifies carbons as CH, CH₂, or CH₃, simplifying structure elucidation by distinguishing quaternary carbons from protonated ones. Practice problems often involve correlating 1H NMR and 13C DEPT spectra to assign carbon types and deduce molecular frameworks.

Key skills include:

Interpreting chemical shift ranges for various carbon types
Using DEPT spectra to differentiate carbon multiplicities
Integrating 1H and 13C data to propose consistent structures
Applying logical reasoning to resolve ambiguous assignments
