上一篇：Electric field generally assists the dissociation of exciplex.
下一篇：Dimer is formed by two same molecules

相关答案

1.There is no ground state for excimer, but exists ground state for exciplex.
2.Compared to monomer emission, the excimer emission is redshift, structureless, but short lifetime.
3.Dipole allowed optical transition occurs between two electronic state with same symmetry
4.In spectra of optical absorption or emission, the rotational energy some time is observable as fine structure
5.According to Franck-Condon principle, and if the environmental influence to the two states is small, the absorption and the emission spectra will be mirror symmetry
6.Franck-Condon shift is a Stokes shift caused by molecular conformation shift
7.The Franck-Condon factor is related to the equilibrium position of the two vibrational stats.The larger the value, the more the overlap, and the stronger the transition.
8.Compared to pure organic materials, metal complexes generally exhibit more strong spin-orbital coupling, as well as more strong phosphorescence
9.Spin-orbital coupling renders triplet state lost its feature and exhibiting some singlet characteristic, which can promote inter system crossing (ISC) and phosphorescent emission
10.Generally, inter system crossing (ISC) is forbidden, spin-orbital coupling can release the forbidden feature
