The NBO Panel

The NBO panel is used to select NBO analysis at the conclusion of the Gaussian job. The panel specifies the type of NBO analysis and which NBOs to save in the checkpoint file. It is illustrated below.

Recommended setings when you will use the NBOs to generate an active space for a CASSCF calculation.

The Type menu specifies the kind of NBO analysis to perform. The Checkpoint Save field allows you to save NBOs and/or NLMOs in the checkpoint file for later visualization (the default is Don’t Save).
