| Abstract: | Infrared radio frequency double resonance effects have been recorded for CF3I with the 9R(12), 9R(14), 9R(16), 9R(18), and 9R(20) laser lines of 12C16O2 and with the 9P(12), 9P(14), and 9P(16) laser lines of 12C18O2. The spectra were recorded at fixed infrared frequency as a function of radio frequency in the range 1–500 MHz. It was found that strong well-resolved spectra could be obtained with the sample cell outside the laser cavity. Of the 471 resonances recorded, 142 were assigned to pure nuclear quadrupole transitions in rotational levels of many vibrational states, 6 of which were identified. Quadrupole coupling constants and magnetic hyperfine parameters were obtained for these states. |
