Jan 30, 2023 · This page takes an introductory look at how you can get useful information from a C-13 NMR spectrum. Taking a close look at three 13 C NMR spectra below. The 13 C NMR spectrum for ethanol.

The 13 C isotope makes only 1% of the isotopes and that is the reason why carbon NMR signals are weaker, and it takes a longer time to acquire a spectrum. In addition, there is what is called gyromagnetic ratio which also affects the signal strength and it is four times lower than that of 1 H.

Carbon-13 (C13) nuclear magnetic resonance (most commonly known as carbon-13 NMR spectroscopy or 13 C NMR spectroscopy or sometimes simply referred to as carbon NMR) is the application of nuclear magnetic resonance (NMR) spectroscopy to carbon.

Unlike proton NMR, which detects hydrogen nuclei, ¹³C NMR specifically targets the carbon nuclei within a molecule. In ¹³C NMR spectroscopy, carbon atoms resonate at characteristic frequencies based on their local chemical environment, which is influenced by neighboring atoms and functional groups.

Feb 8, 2022 · 13 C NMR (proton-decoupled) Just like with 1 H NMR, chemical shift equivalence applies to 13 C NMR. A spectrum produced by a 13 C NMR experiment may not always display a 1:1 ratio of signals to individual carbons atoms.

Identify those carbon atoms which are equivalent (due to symmetry) in a given chemical structure. Predict the approximate chemical shifts of each of the carbons in an organic compound, given its structure and a table of chemical shift correlations.
