" /> multiplicity - CISMeF





Preferred Label : multiplicity;

Detailed label : multiplicity (spin multiplicity);

IUPAC definition : The number of possible orientations, calculated as 2S 1, of the spin angular momentum corresponding to a given total spin quantum number (S), for the same spatial electronic wavefunction. A state of singlet multiplicity has S 0 and 2S 1 1. A doublet state has S 1 2, 2S 1 2, etc. Note that when S L (the total orbital angular momentum possible) there are only 2L 1 orientations of total angular momentum possible.;
