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…
