plotting density of open shell

Hi,

working with an open-shell C(S) symmetric system, I would like to plot the total (alpha+beta) density of the a' and a'' irriducible representations in the xz-plane separately.  From the manual it seems I've to uste TM-5.10, and put some lines into the control file.

It is unclear what lines... what I've understood so far is something like :

$pointval geo=plane
  grid1 vector 1 0 0 range -10,10 points 501
  grid2 vector 0 0 1 range -10,10 points 501
  origin 0  0  0   

however, I think this way I get the total (a'+a'') density into the td.plt file.  Should I modify the first line something like:

$pointval geo=plane mo 1a' 2a' ... up to the last occupied a' MO

to get the total a' (alpha-beta) density ? Smells wrong to me, but this is the best guess I can imagine.
TIA

Hi,

I think, there is no automatic way to do that.
If you use the option
$pointval mo
then each MO is written on seperated files, ordered by symmetry and alpha-beta.
If you want to visualize the density of all the MOs belonging to
the same symmetry, you would have to sum them up somehow.

With
$pointval geo=plane mo 1-10 fmt=xyz
the informations are written as plane 3d coordinates.
Then you have to sum up the values in 4th column, probably using a script.

I hope this helps a bit

Oh, it helps a lot.  It seems this is the way to go.
Summing up density from the various MO is easy.
Thanks,

Hello!

Another way that should work just fine is to edit the control file and comment out first the a' and then the a" orbital occupations, and run "dscf/ridft -proper". This way, only the density of the a'/a" orbitals will be considered in the analysis part.

Have a nice day,
