Introduction Precise measurement of the atomic hyperfine structure attracts more and more attentions for the reason that it WebThe hyperfine constant a in Eq. (1) was also taken to be a scalar quantity for the hydrogen atom however, it is in general a tensor because of the various directional interactions in a paramagnetic species. The hyperfine term in the spin Hamiltonian is more correctly written as S-a-I, where a is the hyperfine coupling tensor.

WebThe hyperfine constant, Fermi contact term, is computed as a function of the interatomic separation for the X 2 ∏ ground state of 17 OH and X 1 ∑ ground state of 107 AgH + molecules.
