Multiplicity about openfermion-dirac HOT 2 CLOSED

For DIRAC there is a fundamental issue as multiplicity is not defined for relativistic calculations. Spin is not a good quantum number when SO-coupling is active. For spin-free calculations this would be possible in principle, but handling this specific case is not implemented in DIRAC as one typically has either closed shell molecules (for which things are simple) or works with a state-averaged energy in which the average is over multiple spin states.

So in short: no point defining this for DIRAC as this information will not be used in the calculations

Alright ! I'll get rid of it in the molecular object then as well as it is just inappropriate here. Thanks !
