| Abstract: | The dipole moments (P
s
) of the T
1
S
→ S
0 transition from the triplet sublevels s = z, y, x, which are determined by the spin-orbit (SO) coupling, are studied for a series of mono- and dichloro derivatives of naphthalene.
Based on the model calculations, the effects of different factors (SO coupling in individual chlorine atoms occupying the
α and β positions in the molecule, SO coupling in the carbon backbone of the molecule, and the compensation effect caused
by the interference of SO interactions in individual structural elements of the molecule) on P
s
are differentiated and discussed. |
