MMsmi(Sval, Ival)

Determinates the quantum numbers of the operators and classify the transitions between energy levels for multisystems.

Parameters:

• Sval (list) – All electronic spins of the system.

• Ival (list) – All nuclear spins of the system.

Returns:

• slit (np.array) – Quantum numbers of the spin operator.

• nlit (np.array) – Quantum numbers of the nuclear spin operator.

• transitions (dictionary) – Possible transitions of the system, cataloged by type.
