15. Summary
The N-O stretching fundamental band of Ar-NO open-shell complex has been measured using a segmented rapid-scan pulsed jet absorption spectrometer based on DFB-QCLs.
Four subbands are identified.
The rotational analysis is still on the way.
Any suggestions and collaborations are welcome!
