The microwave spectrum and molecular structure of CO2–HCl

Abstract

Radio frequency and microwave molecular beam electric resonance spectra have been obtained for three isotopic species of the hydrogen-bonded weakly bound complex CO2–HCl. The following spectroscopic constants have been determined: This complex most likely has a linear equilibrium geometry with an O–H bond length of 2.14 Å. A large induced dipole moment is found in this complex. A comparison of structural properties for this and other related weakly bound molecules is made.
