Abstract
We have carried out two-dimensional measurement of integrated three-pulse photon echo signal of Nile blue doped in poly(methyl methacrylate) (PMMA) at various temperatures (30-230 K). Rephasing and echo formation were still clear even when the population period was extended to >100 ps, indicating that spectral diffusion is a minor process in the picosecond time scale for this sample. The intramolecular vibrational relaxation did not cause a sufficient spectral diffusion.
