Rotational spectrum of 2,2,2-trifluoroacetophenone.

The rotational spectrum of 2,2,2-trifluoroacetophenone has been measured and assigned by supersonic-jet Fourier transform microwave spectroscopy in the 2.0–20.0 GHz region. The measurement has been also extended to all its mono- 13 C substituted species, from which the accurate structural parameters for the carbon skeleton have been determined. [ABSTRACT FROM AUTHOR]
