The Natural Bond Orbital (NBO) program is a discovery tool for chemical insights from complex wavefunctions. NBO 6.0 is the current version of the broad suite of 'natural' algorithms for optimally expressing numerical solutions of Schrödinger's wave equation in the chemically intuitive language of Lewis-like bonding patterns and associated resonance-type 'donor-acceptor' interactions.
Availability and Restrictions
The NBO package is available on Owens. The versions currently available at OSC are:
You can use
module spider nbo to view available modules for a given machine. Feel free to contact OSC Help if you need other versions for your work.
Access for Academic Users
NBO is available to non-commercial users; simply contact OSC Help to request the appropriate form for access.

Usage on Owens
To set up your environment for NBO load one of its modulefiles:
module load nbo/6.0
Here is an example batch script that uses NBO 6.0 via the batch system:
