Abstract

Laser-induced fluorescence excitation spectra of zinc tetrabenzoporphyrin in seeded, pulsed, supersonic expansions of He reveal well-resolved vibrational excitations for the S0→S1 and S0→ S2 electronic transitions. Electronic relaxation in the S1 manifold was interrogated by time-resolved spectroscopy, exhibiting a practical independence of the lifetimes on the excess vibrational energies in the range Ev = 0-10000 cm-1. Spectroscopic line broadening data provided semiquantitative information on interstate electronic relaxation from the electronic origin of the S2 state, whose lifetime is τ(S 2) > 4 ps.
