Abstract
The microwave spectra of three singly substituted isotopic species of fluoro carbonyl chloride, FCOCl, and at least one excited vibrational state have been studied with a molecular beam microwave Fourier transform (MB-MWFT) spectrometer. Because of the high resolution, splittings caused by spin-rotation coupling of the fluorine nucleus have been observed in most transitions. This secondary hyperfine structure served as an identifying label during the process of assigning the spectra of the isotopic and the vibrational satellites. The sensitivity of the spectrometer enabled us to identify the spectrum of the $^{18}O$-isotopomer in its natural abundance of 0.2\% with relative ease.
