These results show the effect of the diffusion of the hydrogen atom, what can be seen that the bonds of the carbon atoms (brown) has increased in length.

description: Brown spheres are Carbon atoms and the green spheres are Hydrogen sites.
We can clearly see that due to the hydrogen site the carbon bond moved.
