a G2Π1/2 ← A2Π1/2 (\({v}^{{\prime} }=0\leftarrow {v}^{\prime\prime }=0\)). b C2Σ1/2 ← X2Σ1/2, showing multiple Δv = 0 bands. The simulated spectra were constructed using the best-fit molecular parameters determined from contour fitting with pgopher78. The x-axis corresponds to the wavenumber of the scanning laser. The rotational branches are noted on the plots, and the spectral features marked by a dashed line denote the band heads. Where branch labels lead to the same arrow, the branches cannot be resolved. The parentheses denote the vibrational transition that the rotational branch belongs to. Error bars correspond to the statistical uncertainty of the count rate at each point.
