Charge transfer metrics

Dear all, 
I would like to do some calculations for charge transfer states with the SOS-CC2 & SOS-ADC(2) methods. I have seen in this paper  that the delta r_NTO descriptor is implemented in MRCC for TDDFT, are there any similar metrics available for wavefunction calculations?

Additionally, I would like to be able to visualise the difference densities between the ground & excited states, is this possible within the program or via the DENSITIES output file?

Thank you!
Esther 

Dear Esther,

The descriptor calculation can be activated using the "guido_ct=on" keyword. At the end of the output, both the ∆r and ∆r(NTO) values are printed.
Please note that, for the ADC(2)/CC2-based methods, the descriptor is evaluated using the singles part of the converged amplitudes, and the NTOs are calculated in the same way. This is actually a fairly good approximation.

Unfortunately, excited-state density is not available at the moment.

All the best,
Dávid
