R2PI DETECTION AND SPECTROSCOPY OF VAN-DER-WAALS COMPLEXES OF 4-FLUOROSTYRENE WITH RARE-GASES

One-color resonance-enhanced two-photon ionization spectra of jet-cooled 4-fluorostyrene van der Waals complexes with Ne, Ar, Kr, Xe are reported. The measured spectra display discrete structure and allow the identification of electronic spectral shirts as well as stretching and bending frequencies of the various complexes. These spectra are interpreted with the help of simple model calculations.
