The range 900–1050 cm-1 studied in this work contains weak Dyad-Pentad and cold Dyad bands transitions of the main isotopologue 12CH . Although rotational methane transitions in the vibrational ground state (GS), as well as those of Dyad and Pentad have been thoroughly investigated [[1], [2], [3], [4], [5], [6], [7], [8]] (and references therein), the HITRAN2020 [9] and other available databases [10,11] do not always correctly describe experimental spectra in some regions.
