Knight shift data of implanted 12 B are used to estimate hyperfine field, H hf (s), and Knight's ξ factor for Al, Cu, Ag, and Au metals at the boron site. In the Rh, Pd, and Pt transition metals the Knight shift and the Korringa relaxation time T 1e are used to estimate the s and d terms of the hyperfine field. In addition to the data from the literature T 1e is measured in Rh metal, and it is proved experimentally that in Rh, Pd, and Pt over T 1e there is no other spin–lattice relaxation mechanism around room temperature. The hyperfine fields at the boron are compared with those at the muon (+) in these metals.
