Zusammenfassung: | The atmospheric-pressure plasma jets and their applications discussed here are a topic of great interest in the fields of science and technology. As is referred to in this paper, the plasma generated in a laboratory setting is described as the dielectric barrier discharge like. The atmospheric-pressure plasma jets of argon (Ar) and neon (Ne) are generated using an ac-power supply with a frequency of 24 kHz and a voltage of 12 kV at room temperature. For the first time in the world in this context, the vibrational spectra Fourier Transform Infrared of coumarin molecule (abbreviated here as 1CMN) dissolved in ethanol and methanol are analyzed after the atmospheric-pressure plasma treatment (APPT) of argon and neon. Plasma jet spectroscopy is used to investigate FT-IR spectra of coumarin before and after APPT process, which takes only 3 min. Also, the changes of structure and the interaction of the plasma and the molecule (coumarin) dissolved in solvents are examined, and the vibration modes of the 1CMN molecule before and after APPT are investigated. Thus, the final structure of the molecule can be explained with respect to the vibrational characteristics of the 1CMN molecule, and the photochemistry of this compound is studied under the conditions of this experiment. |
