[SOLVED] Is there something wrong with NAC calculation?
Dear OpenMolcas developer,
I tested the nac keyword in Alaska module in OpenMolcas-v23.02, accroding to src/alaska/alaska.F90, the "Total derivativate coupling" should be h^AB/(E_A-E_B) + f_CSF^AB, which is "CI derivative coupling" divided by the energy difference of two tagret states plus the "CSF derivative coupling".
However, when it comes to running calculation, it gives:

norm: 0.2536The "Total derivative coupling" is apparently not as the way it should be calculated.The right outcome should be:

------------------------------------------------------------------------------------------When I perform same calculation on version 19.11, it gives the correct answer.
Is there something wrong with NAC code?

Re: [SOLVED] Is there something wrong with NAC calculation?
I think it will be fixed if you use the current master (https://gitlab.com/Molcas/OpenMolcas/-/issues/402).
If you already tried, please post
* The output of "pymolcas version", or the "tag" shown at the top of the output file.
* A full (but short and simple) example that reproduces the problem.

I have complied the latest version and it gives the correct answer, thanks!
