Time-delayed-four-wave-mixing (TDFWM) experiments performed on nile blue and cresyl violet at 5 K using incoherent laser radiation yield a response which depends dramatically on excitation conditions. Fast (femtosecond) and slow (picosecond) processes, variable peak shifts, and type I and II quantum beats are all observed according to the laser frequency ωL and bandwidth ΔωL. We model the TDFWM response on the basis of a site-independent molecular response and an associated inhomogeneous distribution function. These functions are constructed by combining information from TDFWM and fluorescence-line-narrowing (FLN) experiments. © 1996 American Institute of Physics.
