protonikytkentä
Protonikytkentä, often translated as proton coupling or proton linkage, refers to the phenomenon in molecular chemistry and spectroscopy where the magnetic properties of one proton nucleus influence the signal of a neighboring proton nucleus. This interaction occurs through the spin-spin coupling mechanism, where the magnetic field generated by the spin of one proton is transmitted through the bonding electrons to affect the magnetic field experienced by a nearby proton.
This coupling manifests as the splitting of spectral lines in Nuclear Magnetic Resonance (NMR) spectroscopy. Instead
The magnitude of the coupling constant (J) provides valuable information about the spatial relationship and electronic
