Title: INFRARED-RADIO-FREQUENCY DOUBLE-RESONANCE SPECTROSCOPY OF CF, $I^{*}$*

Abstract: Approximately 120 pure quadrupole transitions in more than 6 vibrational states in CF,1 have been observed by means of an infrared-radio-frequency double resonance spectrometer operating near $1075 cm^{-1}$. Double-resonance spectra were observed for five $^{12}C^{14}O_{2}$ and three $^{12}C^{15}O_{2}$ laser lines. The radio frequency source was a 1-500 MHz computer-controlled frequency synthesizer. Although preliminary spectra were recorded with an intra-cavity coaxial cell, the best spectra were obtained with an extra-cavity cell of stripline design. The quadrupole hyperfine structure was calculated by direct diagonalization of the energy matrices. Quadrupole coupling constants obtained for the ground and several excited vibrational states will be compared with previous results obtained by other spectroscopic techniques.
