   # In this example we perform a geometry optimization immediately followed by
   # calculation of frequencies. This is done by setting the task to  
   # GeometryOptimization and by requesting the normal modes in Properties block

   # Note: when using this feature, one might improve the precision if one uses
   # NumericalQuality Good. In order to save time this is not done in this example.
