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
The authors determine the absolute frequency of a key 12.2 GHz methanol transition by measuring related near‑infrared rovibrational lines with an optical frequency comb, achieving…
Precise frequencies of HO lines protected for radio astronomy
Arthémise Altman, Roland Tóbiás, Alexandr S. Bogomolov +5
Precise frequency values have been determined for HO radio lines appearing in protected line lists of the International Astronomical Union and the Panel on Frequency Allo…
Letokhov-Chebotayev intracavity trapping spectroscopy of H
Wim Ubachs, Frank M. J. Cozijn, Meissa L. Diouf +3
In the early days of laser spectroscopy Letokhov and Chebotayev proposed a scheme for measuring narrow spectral lines where the resolution is not restricted to Doppler effects beca…
