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 E_v = 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.
