The temperature-dependence of the electronic dephasing for resorufin in d-ethanol glass was measured from 1.7 to 35 K by incoherent photon echo. The difference between two-pulse picosecond photon echo and incoherent photon echo results was obtained and attributed to spectral diffusion in nanosecond time scale.
