    • The split-off states not only are farther in energy but their mass is not as light as that of LHs which, as we explain below, is central to originate the characteristic behavior of holes in CQDs.

    • In the absence of external magnetic fields, | Fz, ν= k and | - Fz, ν= ,k are degenerate (Kramer doublets) (Ref.). For example, the ground state | 3/2, 1 is degenerate with | -3/2, ,1 . For simplicity of the discussion, in the main text we only discuss the Fz =3/2 states. The reasoning for Fz =-3/2 would be analogous.

    • By analogy to atomic physics, we define as bonding (antibonding) molecular states those having zero (one) node in the direction of molecular coupling. For identical molecules, this is equivalent to symmetric (antisymmetric) parity states.
