Though the polarization dependence of the different peaks are accurately predicted by DFT-ROCIS, the relative emission intensities from different orbitals are not accurately reproduced.This clearly results in a much higher peak associated with |3e -1 3g 6a 1 1g , |1t -1 2g 6a 1 1g states and lacks the sharpness and height of the peaks associated with |1t -1 2u 6a 1 1g , |5t -1 1u 6a 1 1g states. This effect is not only due to the short-coming of quantum chemical method, i.e. DFT-ROCIS used, but also due to absence of dynamical effects in these simulated spectra. Later on we have included and studied the dynamical effects on the RIXS spectra which are discussed below.
