I'm trying to work with triplet state transition using Gaussian DFT. My molecule has heavy atoms and has triplet state emission. I am trying to estimate the emission energy by optmizing triplet excited states. Actually, two triplet excited states (T2 and T1) as the compound shows dual emission.

Could you please help me check if the approach bellow is correct.

I try to get optimized geometries of the second and the first triplet excited state (T2 and T1). If i could get the optimize geometries, i would try to do as follow to estimate emission energies.

- Start with singlet multiplicity; optimized T2 geometry; td=triplet then take the first excitation as emission energy; Similarly for T1.

- DeltaSCF; substract the energy different between two states of the same geometry

But I am having problem with triplet state optimization and also not so sure about the aproach above. Please help!
