We report the fluorescence excitation spectra of the ππ*transition of jet-cooled 3-amino-, 3-amino-N-methyl-, and 4-amino-N-methyl-phthalimide. The spectra are dominated by a long progression of a vibrational mode v' ≈ 210 cm-1in combination with a few vibrational fundamentals of the excited state. The long electronic lifetimes and structural diversity of these compounds make them ideally suited for the study of intramolecular vibronic relaxation. © 1983.
