[molpro-user] spin orbit coupling

[lydia]

Hi every expert,
I used the part of example in page 291 of 2010 molpro manule to
calculate the spin orbit coupling (soc).
 ***,SO calculation for the S-atom
 geometry={s}
 basis={spd,s,vtz}
          !use uncontracted basis
 {rhf;}
          !rhf for 3P state
 {multi
          !casscf
 wf,16,4,2;wf,16,6,2;wf,16,7,2}
          !3P states
 {ci;wf,16,4,2;save,3040.1;noexc}
 {ci;wf,16,6,2;save,3060.1;noexc}
 {ci;wf,16,7,2;save,3070.1;noexc}
 lsint
          !compute so integrals
 {ci;hlsmat,ls,3040.1,3060.1,3070.1;print,hls=2,vls=0}

I get the following output:

   365.15      0.0453

 E0 =   -397.50158387 is the energy of the lowest zeroth-order state
 E1 =   -397.50241574 is the energy of the lowest SO-state

****************************************************************************************************
According to the theory, the 3P state will split to three soc states
(J=2,1,0). I am a little confused with so many energy values.

Does any expert give me some ideas how to analysis the results? I will
be really appreciate.

all the best,
