The number of independent basis


Clicked A Few Times
Hi,

I am currently studying one molecule species with a heavy atom. The total number of the atomic basis in DFT is 328.

         AO basis - number of functions:   328
number of shells: 111

During initialization, 7 linear basis dependencies are found.

WARNING : Found     7 linear dependencies 
S eigenvalue threshold: 1.00000E-05
Smallest S eigenvalue : 7.02178E-10
Largest S eigenvalue : 5.74272E-06

So, the total number of effective basis set should be 321.
This is confirmed by the alpha-beta electron analysis.

  alpha    311    312    313    314    315    316    317    318    319    320
beta 311 312 313 314 315 316 317 318 319 320
overlap 1.000 1.000 1.000 1.000 1.000 1.000 1.000 1.000 1.000 1.000


  alpha    321
beta 321
overlap 1.000

But after I convert the .movecs file to a readable ascii file using mov2asc command,
I find that the MOs are expressed into 328 functions.

So, I'm wondering why shouldn't it be 321 functions?
and How to identify which coefficient is which atomic function, because there are bunch of data with no
explaining words?

Could you please post the first 15 lines of the ASCII converted file?

The output should contain 321 molecular orbitals expressed in terms of 328 atomic orbitals.
Is this what you are seeing?

Cheers, Edo
