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 andJ= 65. Very accurate values of the rotational and centrifugal distortion constants were determined and in particular a more reliable value ofH0= 2.0 10−4Hz has been obtained...

Description
Summary:The ground state rotational spectrum of fluoroacetylene was measured in the millimeter-wave and FIR regions up to 1280 GHz andJ= 65. Very accurate values of the rotational and centrifugal distortion constants were determined and in particular a more reliable value ofH0= 2.0 10−4Hz 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.
