The conformity of an unknown sample with a reference sample is easily assessed by visual spectra comparison, resulting in two categories: IR-identical or not IR For clarity, chemists generally use a technique called broadband decoupling, which essentially ‘turns off’ C-H coupling, resulting in a spectrum in which all carbon signals are singlets.
