AbstractThe rotational spectra of the two structurally related molecules, 1,4-cineole and 1,8-cineole (eucalyptol), were measured between 2–8.5 GHz with chirped pulse Fourier transform microwave spectroscopy. The structures of these two molecules only differ in the connectivity of an ether functional group. This results in a significant change in the three dimensional structure of the molecule and consequently large differences in the rotational spectra. Only one conformer of each molecule was detected in the molecular jet and no line splittings due to internal rotations were detected. A substitution structure (

Copper, silver and gold cyanoacetylides have been synthesized and characterized in the laboratory using a combination of a laser ablation technique and Fourier transform microwave spectroscopy. A study of the chemical bonding helps to understand the preference for metal–C bonding over metal–N bonding.
