*nstate* is the number of states treated simultaneously; *nroot(i)* are the root
numbers to be calculated. These apply to the order of the states in the
initial internal CI. If not specified, *nroot(i)*=. Note that it is
possible to leave out states, i.e.,

STATE,1,2; ! calculates second state STATE,2,1,3; ! calculates first and third stateAll states specified must be reasonably described by the internal configuration space. It is possible to have different convergence thresholds for each state (see
