BSSE calculations
« on: February 01, 2008, 09:35:27 AM »
Hello:
I want to calculate single point energy with BSSE in ri-MP2 level. I tried it with bsseenergy and jobbsse modules but these programs tried to optimize the geometry and I only want the energy. What can I do?

Another question is about the scan. I think the only way to do a scan is with tmole script but it fails sometimes when I want to use aug-cc-pVTZ basis set. Does define script have any option to do a scan?

Regards!!!

Hi,

jobbsse does single-point calculations by default. If you call jobbsse with the option -opt it will perform a geometry optimization.

There is a problem with rimp2prep and the aug-cc-pVTZ basis set. Unfortunately, tmole calls rimp2prep instead of preparing the RI-MP2 input with define as it is the default meanwhile. Please write to the Turbomole support to get a fixed tmole version.

Regards,

Uwe

Is the problem with rimp2prep and the aug-cc-pVTZ basis set still exist?
Is there problem with rimp2prep and the cc-pVTZ basis set?

Hello,

rimp2prep was fixed in 2008, so it works at least since version 5.10. But rimp2prep was just one of several ways to assign auxiliary basis sets for RI-MP2. define, for example, never had problems with aug-cc-pVTZ or other basis sets.
