<div dir="ltr">Hi All,<div>I perform mcscf-ci-so atom calculation for np mp electrons (3p5 4p1 electronic configuration). The  2s+1-L-J atomic term symbols are triplet-D_3,2,1; triplet-P_2,1,0; triplet-S_1; singlet-D2; singlet-P1; singlet-S0 and we expect a total of 36 states in spin-orbit calculation plus the ground state which is singly degenerate.  The state averaging looks right and the  configurations generated in mcscf and ci are as expected. However, in spin orbit I only see 17 states (16+1).</div><div><br></div><div>Am I missing something here in my understanding or state counting? Also there are atomic term symbols like 3D_3 which should generate 7 degenerate states but I dont see that in SO output. Thanks in advance for your help/advice. Amit</div><div><br></div><div>->> input</div><div><br></div><div><p style="margin:0px;font-size:13px;line-height:normal;font-family:Menlo"><span style=""> ***, 3p5 4p1 </span></p>
