Fluorescence spectra of Q-carotene naolecttles in ethanol have been uneasured in a temperaturerange from 20 K to 240 K. Assuming that dephasing of the system is characterized by slow mod-ulation, we obtained temperature dependence of homogeneous and inhonaogeneous broadeningwidths analyzing an almost linear dependence of' the fluorescence peak energy on the excitationenergy. Theoretical calculations of fltrorescence to Raman scattering intensity ratio using thehounogeneous and inhottaogeneous widths reproduce well experimental results. It sttpports that,within a wide temperature range frorn liqvrid to solid phases of solvent, the essential ['eatvtre ofthe optical dephasing process of the system is characterized by the slow modulation.
