We solve the Klein-Gordon equation with the improved Tietz empirical potential energy model. The bound state energy equation has been obtained by using the supersymmetric shape invariance approach. The relativistic vibrational transition frequencies for the 
state of Na2 molecule have been computed by using the improved Tietz potential model. The relativistic vibrational transition frequencies are in good agreement with the experimental RKR values.
