The spectroscopy of mols. doped into superfluid He nanodroplets provides valuable information on the process of solvation in superfluid He. In continuation of an earlier report on emission spectra of various phthalocyanines showing a splitting of all mol. transitions in the range of .apprx.5-12 cm-1, the emission spectra of tetracene, pentacene, and perylene in superfluid He droplets are presented. The new spectra and the results obtained for the phthalocyanines are explained by an empirical model which accounts for the existence of different metastable configurations of a nonsuperfluid solvation layer around the guest mol.
