| Outline of Final Research Achievements |
The sensitivity of the gas analyzer, which consists of a metal-organic framework (MOF) and employs terahertz waves as a probe, was raised. Using this analyzer, the distinction of various gases was demonstrated. In order to detect the transmitted terahertz waves, the infrared sensor was replaced to a new type with a Winston cone as well as the system was reconstructed for a reduction in electromagnetic noise. It was revealed that a spectral peak at 2 THz of ZIF-8 is related to the "open-gate" motion and its intensity is suppressed with adsorption of gas molecules. With estimating the time constant of the decay of the peak, the gas species can be distinguished.

| Academic Significance and Societal Importance of the Research Achievements |
金属有機構造体（MOF）は，原子レベルで均一な細孔をもつ多孔質材料であり，ガスの貯蔵や精製などの応用が見込まれている．本研究ではこれをガス分析の手段として用いるため，ガスがMOFに吸着した際の分子の振動の変化に着目した．高感度の装置で分子のテラヘルツ振動を計測した結果，ガスの吸着過程を精密に測定することができ，それを解析することでガス種の特定が可能であることを実証した．この技術は将来，ガス検知器やガス貯蔵装置の残量メータなどに応用可能である．
