Absorption and circular dichroism line shapes of a molecular dimer in the strong electronic coupling limit

摘要

We have derived approximate analytical expressions for the absorption and circular dichroism line shapes of a molecular dimer composed of two identical molecules (each with a single excited electronic state and single vibrational mode) in the strong electronic coupling limit. These are compared with numerical results and yield excellent agreement. We compare our approach to other theories and discuss experimental applications and possible extensions of this work.
