Analysis of measured high-resolution doublet rovibronic spectra and related line lists of ¹²CH and ¹⁶OH.

ABSTRACT: Detailed understanding of the energy-level structure of the quantum states as well as of the rovibronic spectra of the ethylidyne (CH) and the hydroxyl (OH) radicals is mandatory for a multitude of modelling efforts within multiple chemical, combustion, astrophysical, and atmospheric environments. Accurate empirical rovibronic energy levels, with associated uncertainties, are reported for the low-lying doublet electronic states of ¹²CH and ¹⁶OH, using the Measured Active Rotational-Vibrational Energy Levels (MARVEL) algorithm. For ¹²CH, a total of 1521 empirical energy levels are determined in the primary spectroscopic network (SN) of the radical, corresponding to the following seven electronic states: X ²Π, A ²Δ, B ²Σ^-
