COSMO-RI-ADC(2) optimisations.

[AWPrentice]

Dear TURBOMOLE users and developers,

I'm wishing to run COSMO-RI-ADC(2) optimisations of various excited states. However, everytime I try this I get an error saying this has not yet been implemented - I'm currently using TM v7.4.1.  After reading the COSMO section of the current TURBOMOLE paper it seems that this has been implemented. I was wondering if anyone knew the correct COSMO keywords to include within the control file, or had an example that I could look over as this would be a great help.

Many thanks,

Andrew

What exactly do you mean with 'optimisation'? The calculation of excitation energies or geometry optimizations?

The first one is implemented in the flavor (PTED) published some years back by Lunkenheimer & Köhn.

The gradients published by Khani et al. (Phys. Chem. Chem. Phys., 20, 16354-16363 (2018)) are going to be released with one of the next releases.

It was for geometry optimisations, I had previously looked at the paper you sent and thought that gradients were already implemented in TMv7.4.1.

Thanks for answering my query.

Regards,

Andrew

Gradient with COSMO-ADC(2) were not available in that old version.
