Abstract
Quantum beats in transient absorption of PIC-J-aggregates, modelled by a modified 3-level-system are
calculated. Experimental conditions for the possibility of their observation are investigated. The influence
of the temperature dependent phase relaxation on the temporal evolution of quantum beat signals is
considered.
