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…
Measurement of the Boltzmann constant by the Doppler broadening technique at a 3,8x10-5 accuracy level
Khelifa Djerroud, Cyril Lemarchand, Alexandre Gauguet +7
In this paper, we describe an experiment performed at the Laboratoire de Physique des Lasers and dedicated to an optical measurement of the Boltzmann constant. With the proposed in…
