Abstract

In this paper we report on the line profiles in the absorption spectra for the S₀→S₁ electronic origin and for the 659 and 1394 cm^-1 vibrational excitations in the S₁ manifold of azulene in pulsed, planar, supersonic expansions. The S₁ electronic origin exhibits a Lorentzian line shape, whose homogeneous linewidth results in the lifetime τ = 0.8 ± 0.2 ps for interstate electronic relaxation in the isolated molecule.
