Kd. Zhu, SOLITARY FRENKEL EXCITONS IN ONE-DIMENSIONAL MOLECULAR AGGREGATES WITH STATIC DIPOLE-MOMENT, Communications in Theoretical Physics, 27(2), 1997, pp. 141-144
It is shown theoretically that solitary Frenkel excitons in one-dimens
ional molecular aggregates can exist and propagate when the Frenkel ex
citon is accompanied by a static dipole moment along the aggregate axi
s.
