High resolution FTIR and diode laser spectroscopy of trifluoromethylacetylene and tetrafluoromethane in a supersonic jet expansion
Original language description
We report high resolution infrared spectra in the CF stretching fundamental ranges of trifluoromethylacetylene (CF3−C ≡ C-H, 3,3,3-trifluoropropyne) and of tetrafluoromethane (CF4, R14, PCF14, Halocarbon14). For the experiments a diode laser setup combined with a supersonic jet expansion is described, achieving approximate rotational temperatures between 5 and 10 K for CF4, using a pulsed slit nozzle providing effective optical path lengths of 3 to 4 cm in a single pass. Slightly higher rotational temperatures (near 30 K) for CF3CCH greatly simplify the rotational-vibrational structure of the spectra for this molecule, for which we report also high resolution Fourier transform (FTIR) spectra at room temperature with nearly Doppler limited resolution (instrumental bandwidth 0.001 cm−1) using the Zürich prototype spectrometer ZP 2001 (Bruker IFS125).
