摘要：

The fluorescence rise in solution and in the vapor phase was investigated for the same molecule, dimethyl-POPOP. After optical excitation the structured fluorescence spectrum of the solution evolves in a time shorter than 2 ps. Likewise the fluorescence in the vapor phase rises within less than 2 ps. This finding suggests rapid intramolecular vibrational relaxation in S1 For excitation with a large excess energy of 11000 cm-1 the relaxation to fluorescing states in S1 is still fast under collision-free conditions. © 1979.
