Benchmark measurements of absolute frequencies and collisional line-shape parameters in the CO-Ar system using comb-based FTS
Akiko Nishiyama, Grzegorz Kowzan, Dominik Charczun +2
We report absolute frequency measurements of the CO fundamental band, together with high-precision Ar-induced collisional line-shape parameters using comb-based Fourier-transform s…

Leveraging resonant frequencies of an optical cavity for spectroscopic measurement of gas temperature and concentration
Daniel Lisak, Vittorio D'Agostino, Szymon Wójtewicz +5
We introduce a spectroscopic approach to primary gas thermometry, harnessing precise optical cavity resonance frequencies and ab initio molecular line intensity calculations. By ut…
