The satellite lines belonging to the clusters of tetracene Tc with He are revealed in REMPI spectra of Tc seeded in the supersonic expansion of He. These well-resolved peaks are shifted to the red by 35.7(9) cm−1°relative to the lines of bare Tc. The data by Even et al. (J. Chem. Phys.°115, 2069 (2001)) on the shift of absorption lines for clusters Tc-(He) N allow us to assign this peak to Tc-(He)8 cluster. This result confirms one of the earlier suggested structures of the first layer of He atoms surrounding tetracene in the He nanodroplet.
