A new experiment to test parity symmetry in cold chiral molecules using vibrational spectroscopy
A Cournol, M. Manceau, M. Pierens +21
We present a brief review of our progress towards measuring parity violation in heavy-metal chiral complexes using mid-infrared Ramsey interferometry. We discuss our progress addre…
Characterising molecules for fundamental physics: an accurate spectroscopic model of methyltrioxorhenium derived from new infrared and millimetre-wave measurements
Pierre Asselin, Yann Berger, Thérèse R. Huet +6
Precise spectroscopic analysis of polyatomic molecules enables many striking advances in physical chemistry and fundamental physics. We use several new high-resolution spectroscopi…
High-resolution mid-infrared spectroscopy of buffer-gas-cooled methyltrioxorhenium molecules
Sean Tokunaga, R. J. Hendricks, M. Tarbutt +1
We demonstrate cryogenic buffer-gas cooling of gas-phase methyltrioxorhenium (MTO). This molecule is closely related to chiral organometallic molecules where the parity-violating e…
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…
Measuring the Boltzmann constant by mid-infrared laser spectroscopy of ammonia
S. Mejri, Papa Sow, O. Kozlova +7
We report on our ongoing effort to measure the Boltzmann constant, using the Doppler broadening technique on ammonia. This paper presents some of the improvements made to th…
Microwave spectroscopy of Lambda-doublet transitions in the ground state of CH
S. Truppe, R. J. Hendricks, S. K. Tokunaga +2
The Lambda-doublet transitions in CH at 3.3 and 0.7 GHz are unusually sensitive to variations in the fine-structure constant and the electron-to-proton mass ratio. We describe meth…
