For the 'distance', 'angle', and 'dihedral' constraints (explained above), atom IDs can be replaced by pre-reaction molecule-fragment IDs. The molecule-fragment ID must begin with a letter. The location -of the ID is the average of all atom positions in the fragment. The -molecule fragment must have been defined in the :doc:`molecule ` -command for the pre-reaction template. +of the ID is the unweighted average of all atom positions in the +fragment.

The constraint of type 'arrhenius' imposes an additional reaction probability according to the temperature-dependent Arrhenius equation:
