Several aromatic molecules, including, naphthalene, anthracene, and tetracene, were cooled to less than 1 K in a high-pressure supersonic jet. The temperature was determined from the rotational envelope of the 0-0 electronic transitions in the bare chromophore. From the results, it was deduced that the rotational temperature is ∼ 0.4 K. The excitation spectra of the M·Hen van der Waals complexes formed in the beam (n=1-16) were determined using mass selective threshold ionization.
