Abstract
Dephasing-induced resonances in the nonlinear optical response of mole cular aggregates are expressed in terms or level correlations. The thi rd-order optical response is related to the three-dimensional spectral density function chi(epsilon', epsilon,epsilon E''), Expressions for chi(epsilon', epsilon, epsilon'') derived using the Frenkel exciton mo del show the existence of collective (dephasing-induced) resonances.
