Abstract
The first experimental observation of van der Waals molecules by means of Raman scattering is presented. Ground-state rotational and vibrational spectra of dimers of argon were observed in a supersonic expansion. A dipole-induced-dipole model for the dimer polarizability could accurately reproduce the spectra. With use of a seeded expansion the value of the controversial dimer-to-monomer ratio was directly determined as 0.020(4).Keywords
