Abstract

The Lyman and Werner spectroscopic transitions of molecular hydrogen, the most ubiquitous molecular spectral lines observed in the universe, provide a tool to probe a possible variation of the proton-to-electron mass ratio μ on a cosmological time scale. Such procedures require a database of zero-redshift, or laboratory-based wavelengths at the highest possible level of accuracy. Accurate transitions in the B
