Vibrational ladder climbing of carbon dioxide in an ionic liquid |
要旨(英語) |
By strongly exciting molecular vibrations using infrared pulses, it is possible to control chemical reactions, such as selectively breaking and forming chemical bonds [1]. Recently, we have successfully demonstrated driving of liquid-phase molecular dissociation by employing plasmonic near-fields of mid-IR pulses on a metal surface [2].
The electrochemical carbon dioxide reduction reaction (ERR) is one of the hopeful applications of vibrational excitation, which is an essential pathway to solve global warming. It has been theoretically suggested that ERR can be promoted by vibrational excitation [3]. In this study, we demonstrated to reach a high vibrational level by ladder climbing excitation of molecules in an ionic liquid using infrared femtosecond pulses. In this presentation, we will report on the results of infrared pump-probe spectroscopy experiments.
