| Outline of Final Research Achievements |
Various kinds of new species are produced in the discharge plasma of organic compounds, but many of them are not detected due to their unstability. In this study, we succeeded in ionizing these molecules without fragmentation by near infrared femtosecond laser irradiation, and detecting as intact ions with a mass spectrometer. We have revealed the existence of molecules that are not in normal environments, such as molecules in which carbon chains have been elongated in diacetylene discharge, or molecules in which carbon chains extend from aromatic rings. Based on the present research result, it is expected that the structure and properties of new molecules combined with theoretical calculations and latest mass spectrometry will be clarified.
