What is the effect of deprotonating the ligand on the electron density in the bond then binding it to a pair of Mo(II) ions and its effect NMR peaks?

how does it affect NMR chemical shifts of the NH protons and the N=CH protons in the ligand. what is the observed data/shift/trend and why do signals disappear or shift in the spectrum.
