Considerable progress has been made during these three or four decades in the accumulation of the anomalous emission spectral data of organic molecules, including the emission from higher excited states. In particular, experiments in a supersonicjet expansion provided information on the intrinsic photophysical properties of cooled and isolated molecules in which the Boltzmann distribution is almost negligible. Organic molecules showing emission from higher excited states form unique systems to which a number of modern techniques should be applied to obtain more detailed information on their photophysical properties. These data will provide useful information for understanding the dynamical behavior of isolated molecules in their excited states. There seems to be at least three mechanisms for occurrence of fluorescence from higher excited states: (A) the fluorescence occurs through the thermal repopulation of the lower excited state, e.g., S1; (B) it occurs via the reverse internal conversion from the lower singlet state under collision-free conditions; and (C) it occurs directly from the higher singlet state without involvement of the fluorescence component via the reverse internal conversion from the lower singlet state, i.e., prompt fluorescence. In case (C), the internal conversion rate from the higher singlet state to the lower state is considered to be slow enough to compete with the fluorescence from the higher state. In terms of phosphorescence from higher triplet states, there is mainly one mechanism corresponding to case (A) for the occurrence of the emission, except for the case of halogenated benzenes, for which dual phosphorescence from the 3(∏, ∏*) and 3 (∏, σ*) states was observed. That is, in most cases the phosphorescence from the higher triplet excited state occurs as the result of the thermal activation of the lower triplet state. Further, at present only the T2 phosphorescence is known as an observed emission from the higher triplet e cited state. © 2012 American Chemical Society.
