Structure of the Benzene-Argon Complex in the Gas Phase at 3 Kelvin

Abstract
The structure of the benzene-argon complex is determined from a high resolution band contour of the ν6 transition of the complex measured in a hypersonic jet. It is shown that the argon is located on the main symmetry axis of the benzene molecule. The distance from the center of the benzene ring is found to be 3.4 Å.
