Abstract

The photoelectron spectra of anisole and its van der Waals aggregates with argon (1:1 and 1:2) or carbon dioxide (1:1) have been measured using resonant two-photon laser ionization and a magnetic bottle spectrometer. The influence of the aggregation toward the intramolecular vibrations is discussed. The evaluation of the photoelectron spectra suggests that two different isomers of the anisole¯argon (1:2) aggregate exist in the supersonic beam.
