Carbon-13 - Wikipedia
Carbon-13 (13 C) is a natural, stable isotope of carbon with a nucleus containing six protons and seven neutrons. As one of the environmental isotopes, it makes up about 1.1% of all natural carbon on Earth.
Carbon-13 nuclear magnetic resonance - Wikipedia
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.
Carbon-13 NMR satellite - Wikipedia
Carbon satellites in physics and spectroscopy, are small peaks that can be seen shouldering the main peaks in the nuclear magnetic resonance (NMR) spectrum.

10.9: Carbon-13 Nuclear Magnetic Resonance - Chemistry …
¹³C NMR (Carbon-13 Nuclear Magnetic Resonance) Spectroscopy is a powerful analytical technique used to study the structure and connectivity of organic molecules. Unlike proton NMR, which detects hydrogen nuclei, ¹³C NMR specifically targets the carbon nuclei within a molecule.
Carbon-13 - isotopic data and properties - ChemLin
Carbon-13 - 13 C or C-13 - is a natural, stable isotope of the chemical element carbon, whose atomic nucleus consists of six protons and seven neutrons. As one of the environmental isotopes, it accounts for about 1.1% of all natural carbon on Earth.
Carbon-13 Isotope - (Organic Chemistry) - Vocab, Definition
Explain the key characteristics of the carbon-13 isotope that make it useful for NMR spectroscopy. The carbon-13 isotope, $^{13}$C, has a slightly higher mass compared to the more abundant carbon-12 isotope, $^{12}$C.
19.5: Carbon-13 NMR - Chemistry LibreTexts
2022年10月24日 · In 13 C NMR there is no coupling between adjacent carbon atoms because it is unlikely that both are 13 C, the only isotope of carbon that is NMR active (the odds that two adjacent carbons are both 13 C is \(0.01 \times 0.01\), or \(0.0001\) or \(0.010\%\)).
δ13C - Wikipedia
In geochemistry, paleoclimatology, and paleoceanography δ 13 C (pronounced "delta thirteen c") is an isotopic signature, a measure of the ratio of the two stable isotopes of carbon— 13 C and 12 C—reported in parts per thousand (per mil, ‰). [1]
