Adducts of xenon with organic molecules: Rotational spectrum of dimethyl ether-Xe

A xenon adduct of an open-chain organic molecule, namely, Xe-dimethyl ether (DME), was prepared under the conditions of very low pressure and temperature that exist in the plume following a supersonic expansion. The equilibrium configuration (see picture) and dissociation energy of DME-Xe were deduced from its free-jet millimeter-wave spectrum
