Nonrelativistic calculations (NR) are performed with the TZVPalls2/TZVPall basis set,387 whereas the ECP-based 1c and 2c calculations use the dhf-SVP(-2c) bases.388 Results taken from ref (385). Four-component Dirac–Kohn–Sham (DKS) reference values are taken from ref (389), employing the uncontracted Dyall-VDZ basis.390,391.
