Editing Coupling (physics) (section)

=== Spin-spin coupling ===
[[Angular momentum coupling|Spin-spin coupling]] occurs when the [[magnetic field]] of <dfn>one atom affects the </dfn>magnetic field of another nearby atom. This is very common in [[Magnetic resonance imaging|NMR imaging]]. If the atoms are not coupled, then there will be <dfn>two individual peaks</dfn>, known as a doublet, representing the individual atoms. If coupling is present, then there will be a triplet, <dfn>one larger peak with two smaller ones to </dfn>either side. This occurs due to the [[Spin (physics)|spins]] of the individual atoms oscillating in tandem.<ref>{{Cite web|url=https://chem.libretexts.org/Textbook_Maps/Organic_Chemistry_Textbook_Maps/Map%3A_Organic_Chemistry_With_a_Biological_Emphasis_(Soderberg)/Chapter_05%3A_Structure_Determination_II/5.5%3A_Spin-spin_coupling|title=5.5 Spin-Spin Coupling|date=2015-07-21|website=Chemistry Libretexts|access-date=13 Apr 2017}}</ref>
