PS: Frankly speaking, I am not familiar with EET calculation.

The coefficients between some excited stated are positive (for example: the 1st excited stae of donor and the 1st excited state of acceptor), but I also can see negative coefitiens (for example: the 1st excited stae of donor and the 2st excited state of acceptor). What does negative EET coefficient means? Thank you!
