摘要：

A molecular dipole field (see picture) is created by femtosecond excitation of the title compound, and the response of the environment is observed by stimulated emission spectroscopy of the dye. Strong frequency modulation in the dynamic Stokes shift reflects coherent solvent motion. The IR spectrum of the solvent is related quantitatively to the experiment by dielectric continuum theory.
