# save_ortho_mos

> Save orthonormalized MOs in the EZFIO.

> This program reads the current MOs, computes the corresponding overlap matrix in the MO basis

> and perform a Lowdin orthonormalization : \(MO_{new} = S^{-1/2} MO_{guess}\).

> Thanks to the Lowdin orthonormalization, the new MOs are the most similar to the guess MOs.
