problem with bader and voronoi analysis from cube file

Post by tanguy »

Dear all,

I would like to perform a bader and voronoi analysis from a cube file but a encounter problems.
The system I am studying is a dimer of two molecules. Normally, a partial charge transfer occurs between the two molecules and I would like to quantify them.
For that purpose, I am using the program ORCA from which I can create a cube file. I am then using the bader program to perform a bader and a voronoi analysis in order to obtain the charges.
I have problem visit both the bader and the voronoi analysis.

For the bader analysis, the calculation is performed without problems but the charges I calculate look really strange. Here is the results I obtain:

First, I don't understand why the charge on the hydrogen is equal to 0. Then, when I try to calculate the net charge, I obtain completely unrealistic charges ...
Does anybody know why I obtain such unexpected values?

My problem when I trying to calculate the voronoi charges is that it seems to just don't work. If I am trying to obtain the voronoi charges with the following keywords:
bader -c voronoi -n bader MyElDens.cube

It simply print out the following output:
GRID BASED BADER ANALYSIS (v0.26 07/28/09)

OPEN ... MyElDens.cube

Is there somebody who could help me?

Thanks in advance for the help.

Would you please send the cube files that have problems to twj916@mail.utexas.edu? So that I can look into it and figure out what's going wrong. If the cube files are too large, please just give me a link that I can download the file.
