TMI of strongly coupled excited states

Questions
#1

I want to calculate the transition moment integral (TMI) of S0->Sv stransition, where Sv represents the strongly coupled state. So I used superposition of the wavefunction as the final state as S1+S2 (Tsi) and additionally I need to consider the transition dipole moment (TDM) of both the states (u1+u2). I am attching a file of the derivation and my final result.

Please, go through it and see if it is correct or some problem is there. I would love to get your suggestions. If anyone can suggest anything including any core article where such results are derived.
Thanks
