Under the condition of phase difference given, the bond-length and dissociation energy calculated are quite consistent with the experimental values.

So, when we think about a bond length, this is going to be the length of our bond here, that makes sense because it's going to want to be at that distance that minimizes the energy.

Researchers were able to use Raman spectroscopy to look at the change of the vibrational energy of the bond and then work out the change in bond length.
