Charge analysis after performing riper calculation

Hello,

I have done a riper calculation with Turbomole V.7.7 and it worked fine but after that, I wanted to perform a calculation of the charge (NBO) using proper. The results really confused me because for my system (copper embedded zeolite) I get the wrong charges in the order of 2-3. Are the wrong charges a known issue for the riper module or is there something wrong with the chosen settings? With only one water molecule in a big box, I also get the wrong charges for the system. Thanks for your help.

Kind regards

Dear Danieldeis,

proper does not work with periodic boundary conditions. You have to use Riper for the charge analysis.

Hello Marek,

thanks for your answer. I now tried to add $pop mulliken in the control file but I don't get the partial charges in the out-file. I called riper like this 'riper -proper < control > charges.out ', because I want to perform the calculation of the charge afterward. Did I do something wrong or how do I perform the charges calculation with riper?

Additionally, I would like to ask how can I perform a bond order analysis using riper?

Thanks for your help.

Dear Daniel,

at the moment there is no charge analysis for periodic systems implemented in Turbomole. We are working on it. What you can do is to cut out a cluster from your periodic structure and calculate charges for it.
