Optically Derived Radio-Frequency Benchmark in Methanol: A Sub-kHz Reference for Astrophysical Tests of Fundamental Physics
Frank M. J. Cozijn, Arthémise Altman, Alexandr S. Bogomolov +8
Methanol radio lines observed in space provide sensitive probes of whether the proton-to-electron mass ratio has changed over cosmic time, but such tests require laboratory rest fr…
Methyl mercaptan (CH3SH) as a probe for variation
Paul Jansen, Li-Hong Xu, Isabelle Kleiner +2
Torsion-rotation transitions in molecules exhibiting hindered internal rotation possess enhanced sensitivities to a variation of the proton-to-electron mass ratio. This enhancement…
Prospects for high-resolution microwave spectroscopy of methanol in a Stark-deflected molecular beam
Paul Jansen, Isabelle Kleiner, Congsen Meng +4
Recently, the extremely sensitive torsion-rotation transitions in methanol have been used to set a tight constraint on a possible variation of the proton-to-electron mass ratio ove…
