✦ Synopsis

The microwave spectrum of (\left(\mathrm{CF}{3}\right){3} \mathrm{CCCH}) has been recorded on the NIST Fourier-transform microwave spectrometer. The rotational constant for the principal isotopomer is found to be (B_{0}) (=690.87916) (4) (\mathrm{MHz}) and the dipole moment (\mu_{0}=2.038(8)) Debye. The microwave spectra of the three species with ({ }^{13} \mathrm{C}) substitution on the symmetry axis were observed in natural abundance. Combining rotational constants with the CF bond length and FCF bond angles previously determined in (\left(\mathrm{CF}{3}\right){3} \mathrm{CH}) and (\left(\mathrm{CF}_{3}\right) \mathrm{Cl}) by electron diffraction, the bond lengths and bond angle around the central carbon atom could be determined and are in good agreement with the above mentioned molecules. eci 1993 Academic Press.
