<programming, hardware> The degree to which components depend
on one another. There are two types of coupling, "tight" and
"loose". Loose coupling is desirable for good {software
engineering} but tight coupling may be necessary for maximum
performance. Coupling is increased when the data exchanged
between components becomes larger or more complex.

J-coupling
In nuclear chemistry and nuclear physics, J-couplings (also called spin-spin coupling or indirect dipole–dipole coupling) are mediated through chemical bonds connecting two spins. It is an indirect interaction between two nuclear spins that arises from hyperfine interactions between the nuclei and local electrons. In NMR spectroscopy, J-coupling contains information about relative bond distances and angles. Most importantly, J-coupling provides information on the connectivity of chemical bonds. It is responsible for the often complex splitting of resonance lines in the NMR spectra of fairly simple molecules.
J-coupling is a frequency difference that is not affected by the strength of the magnetic field, so is always stated in Hz.
