Dear Molpro Community, I have inherited the following script: ... {multi,maxit=150;occ,10;closed,1; wf,10,1,0;state,2} {ci,maxiti=50;occ,10;closed,1;core,1; wf,10,1,0; state,4,nstatei=7} I was not able to find any reference to the nstatei parameter. Can anybody enlighten me about this nstatei ? Thanx, Akos
