Calculation of spin orbit coupling constant
Hi everyone,
I am a very newbie to DALTON, so right now I am having a project which is related to calculate the spinorbit coupling constants Hso between First Lowest Singlet and Triplet Excited States, calculated at B3LYP/631G(d)//M06. My molecule is BODIPY, you can check it at this paper: " Theoretical Determination of Electronic Spectra and Intersystem Spin−Orbit Coupling: The Case of IsoindoleBODIPY Dyes" (dx.doi.org/10.1021/ct500426h  J. Chem. Theory Comput. XXXX, XXX, XXX−XXX)
Can you help me to edit input file?
Thank you so much

Re: Calculation of spin orbit coupling constant
I suggest that you email the authors of that paper and ask them to send you a copy of the relevant dalton input files.

Re: Calculation of spin orbit coupling constant
You have to look at the log file, there is no error message in the output file. One guess is that your disk ran full, the 2electron spinorbit integrals will use a lot of disk space.

Hi xiongyan, I have no idea about 2016.2 ver, in my case, I run with Dalton 2018.2 ver, so I did not see this error.xiongyan21 wrote: ↑28 Sep 2019, 04:56I have tried it using Dalton2016.2, and found the output is slightly different

Re: Calculation of spin orbit coupling constant
I should recompile Dalton2018.2 when I am free, because I have upgraded Ubuntu.
Using Dalton2016.2, it seems the calculation can move on， but I am not sure wether it can finish.

Re: Calculation of spin orbit coupling constant
Really, in my case, I do not think it is error, i do not know when I try to run with the small molecule like methane, water, benzene,... everything is fine, however, with the big molecule like BODIPY (borondipyrromethene), it keeps repeating like the output I attached, no error occurred but the calculation can not keep moving on.xiongyan21 wrote: ↑28 Sep 2019, 06:06I should recompile Dalton2018.2 when I am free, because I have upgraded Ubuntu.

Re: Calculation of spin orbit coupling constant
Based on the warnings in the output file:
I'm guessing you do not want to use symmetry generators in your input which generate atoms in addition to those that you give in the input? If so remove "Generators=1 XY" from your molecule input file. Unfortunately, I don't know how to prepare the Dalton input file for what you want to calculate so I can't help with you with that part.
Min HX interatomic separation is 0.2935 Angstrom ( 0.5547 Bohr)
Min YX interatomic separation is 0.4151 Angstrom ( 0.7843 Bohr)
@ WARNING: Number of short HX and YX bond lengths: 2 11

Thank you so much for your comments. I will try to do that. Actually, my target is very simple, I need to get the value of spinorbit coupling constant value as reported in the paper I attached inside my post. Simply explain about my calculation is, I need to calculate spinorbit coupling constant value which will be used to evaluate for the efficiency of intersystem crossing (transition from excited singlet S1 to excited triplet T1)
As you can refer from this table of paper: https://drive.google.com/file/d/1S_WLY1 ... oItEs/view.

Re: Calculation of spin orbit coupling constant
Dear Dr. Olsen
I think you are correct, because I do not know whether the original input can produce the correct result, and the input should be prepared by a Dalton professional when he absolutely know the aims of the calculation. I am not interested in this calculation, discarded the log file, and will never try it forever.
Very Best Regards!
