CCL: Theoretical calculation of Quantum yield



Respected CCL users,

I want to calculate the quantum yield of absorption/emission process using quantum mechanical methods, (preferably by writing my own code or using some software).
Is it possible to do so? If yes, then kindly suggest me some references (articles, books etc.) which explain(s) elaborately about the technique to do this.

Waiting for your kind reply

With best regards,
