| Outline of Final Research Achievements |
A cavity ringdown absorption spectrometer was build to observe the A-X transition of Criegee intermediates. Combined with a discharge flow cell, a spectral survey of the simplest Criegee intermediate, CH2OO, was carried out in the region of 600-700 nm using the newly built spectrometer. However, absorption spectra originating from CH2OO have not been observed so far, mainly because of the interference of strong I2 absorption. A new generation method of the intermediate, which does not generate I2 molecules, is required for a further survey of the A-X transition of the intermediates.
