The Photochemistry of Small van der Waals Molecules as Studied by Laser Spectroscopy in Supersonic Free Jets

  • Donald H. Levy

Abstract

We have used a seeded supersonic free jet expansion to prepare van der Waals molecules consisting of one or more rare gas atoms weakly bound to a seed molecule (the substrate) by attractive van der Waals forces. The electronic spectrum of these van der Waals molecules appears as a satellite to the electronic spectrum of the uncomplexed substrate molecule, and we have used laser induced fluorescence spectroscopy to study both the structure and photochemistry of these molecules.1
