The accuracy of the molecular spectroscopy on weak transitions (too weak to saturate) in molecules which cannot be cooled and trapped, is presently limited to the sub-megahertz level, without clear perspectives for further substantial improvements. We demonstrate a new method with the potential to achieve kilohertz-level accuracy. We bring the Doppler-regime measurements into the high-pressure...

37. Improved determination of the dissociation energy of H2

Cunfeng Cheng (Vrije Universiteit Amsterdam)

oral without proceeding

The dissociation energy (D$_0$) of H$_2$ is a benchmark value in quantum chemistry, with recent QED calculations now approaching accuracies achievable in simple atoms. Precise measurement of the GK-X molecular transition, in combination with other precision measurements, provides a determination of D$_0$. The GK-X transition is excited through Doppler-free two-photon spectroscopy using 179-nm...
