i only need question 14 thank you

We consider the binuclear complex depicted below where A and B are paramagnetic transition metal ions with spin values SA and S8 respectively; O is the 02. bridging the metal ions. + O L -BL LAL 14- Draw the overlap integral between the magnetic orbitals. Is it null or non-zero? Justify and deduce the nature of the exchange interaction when the angle is 90. at high and at low
