<div dir="ltr"><div><div></div>I carried out SA-MCSCF calculation for 2 singlet states and 1 triplet state. From the MCSCF calculation, I see that the charge densities are stored in sets 2 and 4 for the two singlet states and in set 6 for the triplet state.<br><br></div>When I do a POP analysis, for the singlet state (by specifying the set=2 and spin=0), I get the following eror message, which suggests that MS2=2 for all the sets (2, 4, 6). <br><br>?REQUESTED DENSITY NOT FOUND IN RECORD 2101.2 FOR STATE= 1 SYM= 1 MS2= 0 TYPE(S)=CHARGE<br><br> THE RECORD CONTAINS THE FOLLOWING MCSCF DATA:<br> ORBITALS/MULTI SET= 1 STATE= -3 SYMMETRY= 1 MS2= 2 NELEC= 4<br> ORBITALS/DIABATIC SET= 2 STATE= 0 SYMMETRY= 1 MS2= 2 NELEC= 4<br> DENSITY/SPIN SET= 1 STATE= 1 SYMMETRY= 1 MS2= 2 NELEC= 4<br> DENSITY/CHARGE SET= 2 STATE= 1 SYMMETRY= 1 MS2= 2 NELEC= 4<br> DENSITY/SPIN SET= 3 STATE= 2 SYMMETRY= 1 MS2= 2 NELEC= 4<br> DENSITY/CHARGE SET= 4 STATE= 2 SYMMETRY= 1 MS2= 2 NELEC= 4<br> DENSITY/SPIN SET= 5 STATE= 1 SYMMETRY= 1 MS2= 2 NELEC= 4<br> DENSITY/CHARGE SET= 6 STATE= 1 SYMMETRY= 1 MS2= 2 NELEC= 4<br> DENSITY/CHARGE SET= 7 STATE= -3 SYMMETRY= 1 MS2= 2 NELEC= 4<br> DENSITY/SPIN SET= 8 STATE= -3 SYMMETRY= 1 MS2= 2 NELEC= 4<br> GROUP/DIABATIC SET= 1 STATE= 0 SYMMETRY= 1 MS2= 2 NELEC= 4<br> OCC/DIABATIC SET= 2 STATE= 0 SYMMETRY= 1 MS2= 2 NELEC= 4<br> EIG/DIABATIC SET= 2 STATE= 0 SYMMETRY= 1 MS2= 2 NELEC= 4<br><br clear="all"><div><div><div><br>In fact, when I change the order of the singlet and triplet states in
the SA-MCSCF calculations (i.e, set 2 contains the triplet state charge
sensity and sets 4 and 6 contain the singlet state charge density, I see
MS2=0 for all sets in the orbital record). From this, it appears that
MS2 values in the orbital record reflect the spin state corresponding
to the last state in the MCSCF calculation. <br><br></div><div>Although I can do a POP with just set=iset (and no spin card), but I would like to know what is happening here.<br><br></div><div>Thanks in advance.<br><br></div><div>Sabyashachi Mishra<br>
