| Outline of Final Research Achievements |
CH5+ molecular ion has been detected by mass analysis in lab and on the satellite Titan of Saturn, and the infrared spectrum of CH5+ has also been observed in laboratory. Although the detection of the interstellar CH5+ is expected, it has been hindered by the failure of the spectral assignment for long time. In the present study, we aimed to reveal the spectral assignment for CH5+ by the infrared double resonance.
Although we can observe the infrared spectrum of CH5+ by the highly sensitive cavity ring-down spectroscopy, we failed to observe the CH5+ signal of infrared double resonance with a cw laser and a pulsed laser. Since there is no previous example for the observation of mid-infrared double resonance of molecular ions, the present work should be an importance step towards the future realization.
