In the context of two-dimensional NMR spectroscopy, 'dept' refers to Distortionless Enhancement by Polarization Transfer, a technique used to enhance the signals of certain types of carbon atoms in a sample. This method allows for the differentiation of carbon types based on their connectivity and provides clearer insights into the molecular structure by selectively enhancing signals from CH and CH2 groups while suppressing those from CH3 groups. This results in a more informative spectrum that can help identify functional groups and structural features within organic compounds.
congrats on reading the definition of Dept. now let's actually learn it.
