NMR data are computed for the 1st and 3rd nucleus only. The UIK subkey is used to indicate that certain terms are to be included in the "U-matrix", which goes into the first-order change of the MO's due to the applied magnetic field. See the documentation (Utilities) for more information.
The "BEST" specification means that the mass-velocity and Darwin terms are included for a scalar relativistic calculation. In a non-relativistic run it has no meaning. In a spin-orbit run it would include the Fermi-contact term for the Pauli formalism, and the ZORA Spin-Orbit terms for a ZORA calculation.
NUC 1 3
The other two calculations are similar, apart from the specification of the applicable relativistic features.
