Webb22 juli 2024 · For singlet–singlet excitations, we cross-validate them on six benchmark sets that cover small to medium-sized chromophores with different excitation types (local-valence, Rydberg, and charge transfer). WebbThe main difference between singlet and triplet states is that the triplet state is more stable than the singlet state. This is because triplet states have two unpaired electrons, while singlet states only have one unpaired electron. The triplet state is also higher in energy than the singlet state.
