    • Note that a more complex spectroscopic pattern is observed at lower temperatures with the number of low-energy Raman lines exceeding that expected for these molecules on the base of the calculations (see Figure S3 in the Supporting Information, The additional lines could be caused by crystal-field splitting see ref, 16, as well as by different cluster positions inside the cage.

This can be explained by the importance of the correlation effects for the highly localized 4f orbitals. It was shown for Gd that conventional DFT methods significantly underestimate the splitting between occupied and unoccupied 4f bands and the energies of unoccupied 4f-based states.[22a] At the same time, the energies of 5d and 6s bands are predicted with reasonable accuracy, 22a] Hence, we consider that the gaps for spindown orbitals predicted in this work for GdxSc3-xN@C80 are affected by the inadequate treatment of the vacant 4f orbitals of Gd, and hence physically meaningful values can be obtained only for spin-up orbitals, which are therefore discussed here. Note that the description of the 4f states can be improved by introduction of
