Lamb-Dip Millimeter-Wave and High-Resolution Far Infrared Spectra of HCCF.
The ground state rotational spectrum of fluoroacetylene was measured in the millimeter-wave and FIR regions up to 1280 GHz and J = 65. Very accurate values of the rotational and centrifugal distortion constants were determined and in particular a more reliable value of H0 = 2.0 10(-4) Hz has been obtained compared to that previously determined of -0.30 Hz. HCCF was prepared in a dc glow discharge in presence of 1,3,5-trifluorobenzene. Copyright 1998 Academic Press.
