Task
In this example the nucleophile substitution of a Cl- by another Cl- in CH3Cl is simulated using bluemoon sampling.
Input
POSCAR
In the blue moon sampling method several POSCAR files are used for different values of the collective variable.

- For isolated atoms and molecules interactions between periodic images are negligible (in sufficiently large cells) hence no Brillouin zone sampling is necessary.
