3.5.13 Natural Bond Orbital Package ($nbo)

When NBO is set to TRUE in the $rem section, a natural bond orbital (NBO) calculation is performed, using the Q-Chem interface to the NBO 5.0 and NBO 6.0 packages. In such cases, the $nbo section may contain standard parameters and keywords for the NBO program.
