Besides, the ratio of the absorption coefficients between singlet states and singlet-triplet states, and that of probability of collision energy-transfer were measured.
此外还测定了单重态和单-三重态间的吸收系数之比以及能级间的碰撞转移几率之比。

We have used the perturbation theory to calculate the energy bands of the bipolaron and the free-polaron, in order to investigate the stabilities of the singlet and the triplet bipolaron states.
