CCL:G: Error using SaveNBOs in Gaussian for NBO Calculations



 Sent to CCL by: Jamin Krinsky [krinsky.jamin#gmail.com]
 Hi Pritha,
 I have not heard of being able to visualize NBOs without using the
 savenbos keyword. I think the error message you got is due to the
 program having a built-in limit of the number of orbitals that can be
 saved. It is built into the NBO3.1 program and I think it's 500 in
 G03, so 88 atoms with a fairly large basis will probably surpass the
 limit. If you have the source code you can change that and recompile
 G03 with the modified NBO code, see the NBO manual for discussion of
 that. Or you could buy NBO5 and compile that with G03 or G09 (again
 assuming you have the Gaussian source code).

  I'd appreciate any further guidance you could provide.
