Accurate determination of the Boltzmann constant by Doppler spectroscopy: Towards a new definition of the kelvin
Benoît Darquié, Sinda Mejri, Papa Lat Tabara Sow +6
Accurate molecular spectroscopy in the mid-infrared region allows precision measurements of fundamental constants. For instance, measuring the linewidth of an isolated Doppler-broa…
A revised uncertainty budget for measuring the Boltzmann constant using the Doppler Broadening Technique on ammonia
Cyril Lemarchand, Sinda Mejri, Papa Lat Tabara Sow +6
We report on our on-going effort to measure the Boltzmann constant, kB, using the Doppler Broadening Technique. The main systematic effects affecting the measurement are discussed.…
Evidence for speed-dependent effects in NH3 self-broadened spectra: towards a new determination of the Boltzmann constant
Meriam Triki, Cyril Lemarchand, Benoît Darquié +4
In this paper we present an accurate analysis of the shape of an isolated rovibrational ammonia line from the strong nu2 band around 10 m, recorded by laser absorption spectrosc…
Progress towards an accurate determination of the Boltzmann constant by Doppler spectroscopy
Cyril Lemarchand, Meriam Triki, Benoît Darquié +3
In this paper, we present significant progress performed on an experiment dedicated to the determination of the Boltzmann constant, k, by accurately measuring the Doppler absorptio…
