We present a direct observation of an ultrafast time-resolved emission spectrum of a dye molecule in solution, the time resolution of the system being 2× 10− 12 sec. Vibrational relaxation within the vibrational manifold of the excited electronic state of rhodamine 6G occurs within 6× 10− 12 sec. We discuss the implications of these results for the understanding of homogeneous broadening of excited electronic states of large molecules.
