Hi,
Can anybody tell me please how can I calculate NMR chemical shifts using Gaussian 03.

Use the keyword "NMR" in the route section.

To see this, login to the WebMO working Demo and run a Gaussian job with the Calculation set to "NMR"

G'day!
I want to include one or more point charges in a single point calculation.
I guess the keyword is "charge" in the method line?
What is the format at the end of the input file?
Blank line
x y z charge {each with one dec place?} {anything else here?}
blank line
?
Is there a way of setting placing it using gaussview? Like with a dummy or ghost atom or otherwise?
Has someone got a link to a sample input file somewhere on the web?
Cheers

Hi!
How can I change the percentage of HF exchange in B3LYP with Gaussian03? Thanks

HI all...
here is my question:
Im trying to find through NRT analysis, in Gaussian 03W, the bond orders of an mycosporine compound, My input line is the next one:
# b3lyp/6-31+g(d,p) pop=nboread

(Z-matrix)

$NBO BNDIDX RESON NRT $END

The program show me all NBO analysis and Wiberd bond orders but i cannot visualizate results of NRT analysis.
I made the test to calculate with only these aditional NBO keyword over water molecule having the same results:
$NBO NRT $END

If you can tell me how can i obtein and view NRT analysis i will be grateful with you.
Can be usin a iop() instruction maybe???
Thanks!

You cannot view the NRT analysis results in WebMO. You need to look directly in the output file.

Hello,

Is there a special keyword for the scaling factor, alpha, in computing solvation free energies in Gaussian 03? We assigned different alpha values (see below), but get exactly the same solvation free energies.
We have the new version Gaussian 09, but we are using an older version of Gaussian because we optimized all of our geometries in Gaussian 03.
Thank you!

Howdo,

I'm trying to model O2 binding on Pt2 using two different basis sets (lanl2dz for Pt2 and ub3lyp/6-311++ for O2). How can this be done?

Many thanks!

Dear All,

I would like to apply different voltages to a system from Gaussview, I know the "POLAR" keyword but not how to define the voltages and, in this case how to put the keywords in gaussview. Can somebody help me? Thanks a lot,

Alex

i want to use CCSD(T) to compute binding energy using Etot = E(AB) - (E(A) + E(B)). I created a test geometry MeOH (say "A") to optimize geometry first, but received following error below from output deck. What can i do? thx for any help

Dear All,
I want to do a NRT calculation using NBO3 and Gaussian9. I am using the command
pop=NBORead
Molecular specification
$NBO NRT $End

but this is not giving me the NRT bond order. What do u suggest to get the NRT bond order.(covalent/ionic/total)

Thanks !!

can anyone answer why the computer calculated bond length of O2 is 1.5 while its real bond length is 2?

Hi, I just started to use Gaussian03 for my research. (My major is mechanical engineering and no one in my lab have no experience on this program before... )

I have problem about simple CsCl optimization program.

I struggled to fix this for 1 week and couldn't finished this...

Would you please help me to find out what is wrong??


* I used https://bse.pnl.gov/bse/portal for basic sets(3-21G) and just ctrl+c and ctrl+v on my program

Hi,
I'm doing a multilayer ONIOM calculation which optimized successfully, but the frequency will not calculate. Does anyone have any advice?
