We used MOLCAS6.4 to calculate SOC in the surfacing crossing point(triplet-singlet PES crossing). According to explanation in the user's manual, I used the Douglas-Kroll Hamiltonian and the AMFI integrals as well as the RASSI module. The work seems finished normally.
The spin-orbit section gave the information as
follows, I have no idea about how to get the SOC constant from these numbers.
Eigenvalues of complex Hamiltonian:

Thanks a lot.
