Abstract

In this paper we report the results of an experimental study of the fluorescence excitation spectra and of the time-resolved emission of Zn-tetraphenylporphyrin (ZnTPP) and of free-base tetraphenylporphyrin (H2TPP) seeded in pulsed supersonic expansions of He. We have studied the S ₀→S₁ transition (the Q band) and the S ₀→S₂ transition (the Soret, B band) of ZnTPP, as well as the S₀→S₁^α, transition (the Q_x band), the S₀→S₁^y transition (the Q_y band), and the S₀→S₂^x transition (the B_x band) of H₂TPP. Information was obtained on the electronic energy levels, the vibrational level structure, the details of low-frequency nuclear motion, and some characteristics of electronic relaxation.
