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

Isotopes of carbon - Wikipedia
There are three naturally occurring isotopes of carbon: 12, 13, and 14. 12 C and 13 C are stable, occurring in a natural proportion of approximately 93:1. 14 C is produced by thermal neutrons from cosmic radiation in the upper atmosphere, and is transported down to earth to be absorbed by living biological material. Isotopically, 14 C
Carbon-13 NMR - Chemistry LibreTexts
Jan 30, 2023 · Carbon-13 Nuclei as Little Magnets. About 1% of all carbon atoms are the C-13 isotope; the rest (apart from tiny amounts of the radioactive C-14) is C-12. C-13 NMR relies on the magnetic properties of the C-13 nuclei.

Carbon-13 | isotope | Britannica
Cobalt-60 is the longest-lived radioactive isotope of cobalt, with a half-life of 5.27 years. It is produced by irradiating the stable isotope cobalt-59 with neutrons in a nuclear reactor. Cobalt-60 is used in the inspection of materials to reveal internal structure, flaws, or foreign objects and in the sterilization of food.
Carbon 13 - an overview | ScienceDirect Topics
Carbon-13 (13 C) is a stable and nonradioactive isotope of carbon, and, in contrast to the common carbon-12 isotope, can be detected with MRS. However, the low natural abundance of 13 C (1.1%) combined with its relatively low intrinsic sensitivity (∼1.6% of 1 H) make conventional 13 C-MRS very demanding in terms of signal detection.
