coupling constant (spin-spin), \(J\)

https://doi.org/10.1351/goldbook.C01383
A quantitative measure for nuclear spin-spin, nuclear-electron (@HT07052@) and electron-electron (fine @C01025@ in EPR) @C01025@ in magnetic @R05326@ @S05848@. The 'indirect' or scalar NMR @C01025@ constants are in a first approximation independent of the external magnetic field and are expressed in \(\mathrm{Hz}\).
