    • 2,3 has not been addressed. Typically, the resulting strong gauge dependence of the calculated NMR shieldings has been reduced by choosing highly symmetric molecules only. Furthermore, the CHF approach means that the important correlation effects have not been addressed in these studies.

    • 6+ ion has been chosen because it is a closed shell system. In this way, SCF convergence problems as well as issues related to the occupation of the various valence shells are avoided. Results for a neutral U atom are, of course, very similar.

    • note
    • Note that, for Pauli (QR) calculations, nonrelativistic basis sets have to be employed whereas in ZORA calculations, specially optimized ZORA basis sets have to be applied. In other words, Pauli and ZORA calculations do not use basis sets with the exactly same exponents. See, e.g., ref 35 for a discussion of this point.
