Abstract : Lifetimes of excited states can be determined not only at high pressures, but also at low pressures. The former gives but a single value for the electronic state, whereas th latter gives a different answer for as many vibrational substates of the electronic state as can be excited by absorption of light. This new method, termed vibronic lifetime spectroscopy, has been successfully demonstrated for beta-naphthylamine. Such measurements are a direct test for dynamic theories for photochemical intermediate states. (Author)
