20.2.5 Defining the state symmetry

The number of electrons and the total symmetry of the wavefunction are specified on the WF card:



is the number of electrons
is the number of the irreducible representation
defines the spin symmetry, spin$=2S$ (singlet=0, doublet=1, triplet=2, etc.)

The WF card must be placed after any cards defining the orbital spaces OCC, CORE, CLOSED.

The REF card can be used to define further reference symmetries used for generating the configuration space, see REF. 2018-06-19
