CCL:G: NBO Analysis



Hi Anthony,

There are some methods / softwares to plot NBO.

1. NBOview

2. ChemCraft

3. use the keyword pop=(nbo,SAVENBOS) in Gaussian 03/09, then the MO data in checkpoint file will be replaced by NBO. Open the checkpoint file with GaussView, and plot NBO.

4. use my NBO2Molden program. It can save NBO graphic files in Molden format. Then you can plot NBO using Molden or GabEdit.

Hi,

I am trying to visualize natural bond orbitals from a Gaussian 03 calculation.
Here is a sample input file:

=====================
Chk = JOB
#p HF/LANL2DZ NOSYMM POP=(FULL,NBOREAD,SAVENBO) GFOLDPRINT

ATOM COORDINATES HERE

$nbo plot $end

=======================


The .log file has NBO analysis (I believe my inputs to "POP" are correct). Also, I obtained an .37 file.

I've been reading past messages, and I've followed the direction for Molekel 4.3 (the only thing different is that I included the savenbo option and full). LINK : http://www.ccl.net/chemistry/resources/messages/2007/04/05.011-dir/index.html

However, I have Molekel 5.4, and I don't see an option to load the .37 file. When I choose "surfaces" -> "electron density," I obtain what appear to be molecular orbitals.

Can anyone tell me where I can obtain molekel 4.3 or another viable molecular visualizer? Please correct me if I am doing something wrong.

Thanks.
