This video discusses why 13C NMR spectra are not integrated like 1H NMR spectra. Signal integration is very useful for determining how many hydrogens are present in a 1H spectrum. 13C spectra are rarely integrated because of differences in how carbon nuclei "relax" and emit signal during spectrum acquisition. Specifically, quaternary carbons relax very slowly and show very weak signals in a 13C spectrum. Therefore, in 13C NMR it is not worthwhile to compare peak size to determine the number of carbon nuclei in a spectrum.
