[SOLVED] Non-adiabatic coupling description

Hi

I am computing non-adiabatic coupling, and I would like to know which are the "g" and "h" vectors printed in the output file?

This is my input file:

&GATEWAY
        Tinker
        basis = 6-31G*
        group =  C1

 &SEWARD

 &Espf
        External = Tinker
        lamorok

 &RASSCF
        JobIph
        CIrestart
        nactel= 12 0 0
        ras2= 11
        inactive=58
        ciroot=2 2 1

 &RASSI
        nrof jobiphs
        1 2
        1 2

 &ALASKA
        NAC= 1 2

and this is my output file regarding ALASKA module:

()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()

                                              &ALASKA

                                   only a single process is used
                       available to each process: 5.0 GB of memory, 1 thread

I'll appreciate any info about the handling of these matrices.

Re: [SOLVED] Non-adiabatic coupling description

See https://doi.org/10.1021/acs.jctc.6b00384

"CI derivative coupling" is h^AB
"CSF derivative coupling" is CSF^f^AB
"Total derivative coupling" is f^AB (eq. 6)

Re: [SOLVED] Non-adiabatic coupling description

Thanks a lot, Ignacio. To get the gradients of the two states (g^A and g^B) should I to add PNEW keyword to the input file right? If it is yes, how exactly would be if I want the gradients for S0 and S1 states?

I am using the 8.2 version, and I was wondering if the 8.4 version gives a different (more detailed) information regarding NAC calculation in the output file? e.g., orthogonal and normalized vectors   x̂ and ŷ directly in the output file.

Thanks

Re: [SOLVED] Non-adiabatic coupling description

I don't think you need PNEW (the manual says the gradient is not printed, that's not true in my experience). You just need to run separate gradient calculations with ROOT=1 and ROOT=2 (or set the default root with RLXRoot in RASSCF). The orthonormalized vectors, etc. only make at an intersection point (while the NAC can be computed at any arbitrary geometry). OpenMolcas (and I think molcas 8.2 and 8.4 too) will print all this info after a successful CI optimization. You can "force" convergence on such optimization by setting a very large threshold.
