Abstract

The electronic origin band of the S1 <- S0 transition of monomer phthalocyanine doped into liq. helium droplets consist of a single zero phonon line (ZPL) and a structured phonon wing. The latter reflects the low frequency modes of the helium droplet. At very high resoln. (1 MHz) the asym. spectrum of the ZPL of phthalocyanine provides no indication of a rotational substructure. Changes in the asymmetry and the peak position of the ZPL with variation of the av. droplet size are in very good agreement with an inhomogeneous model line shape.
