Adducts of Xenon with Organic Molecules: Rotational Spectrum of Dimethyl Ether–Xe

Authors


Abstract

original image

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.
