Abstract
The determination of the structure of the dimethyl ether (DME)-CO(sub 2) complex from the ground-state moments of inertia and an estimation of the binding energy of DME-CO(sub 2) in the gas-phase calculated from the rotational spectroscopic parameters is presented. The inspection of the binding energies highlights that the bonding in DME-CO(sub 2) is stronger than in many complexes of dimethyl ether (DME).
