Abstract
The rotational spectra of two isotopologues of the molecular complex CF3Cl-dimethyl ether have been measured with pulsed jet Fourier transform microwave spectroscopy. The rotational spectrum encodes information on the global minimum configuration, stabilized by a Cl···O halogen bond, and on the almost free rotation of the -CF3 group.
