Fig. 5: Visual representation of DFT-calculated frontier molecular orbitals for CuX-1 complexes.
From: Cu(I)-thioether coordination complexes based on a chiral cyclic β-amino acid ligand

The figures depict (a) side and top views of LUMO for CuCl-1. b side and top views of HOMO for CuCl-1. c side and top views of LUMO for CuBr-1. d side and top views of HOMO for CuBr-1.
