-The electronic basis set can be freely chosen from the [[https://www.molpro.net/info/basis.php|Molpro basis set library]].

At the current stage no user defined mixed basis sets are possible within the NEO programs. 
  
 The nuclear basis set is defined via the **''nucbas''** keyword. The default basis for nuclear basis sets must be defined in every case as the **''neo-basis''**. Afterwards, the selected NEO centers can be assigned with the desired basis set. It is highly recommended to use the specifically tailored [[https://doi.org/10.1063/5.0009233|PB basis sets]] for multicomponent methods developed by Hammes-Schiffer and coworkers. Note that all NEO centers need to be assigned individually with the same basis set. The nuclear basis set is defined via the **''nucbas''** keyword.
