Extended Data Fig. 3: Location of the bandheads in the $${0}^{{\prime} }\leftarrow {0}^{{\prime\prime} }$$ 0 ′ ← 0 ″ rovibronic transitions.

The bandhead locations are indicated with green arrows. The red dots represent the measured data while the blue line is the best fit to the data (see Methods for the details of the fit). The x-axis corresponds to the wavenumber of the first laser used in the excitation-ionization scheme, Doppler-corrected to the molecular rest frame and shifted by \({{{{T}}}}_{{\Pi }_{1/2,0}}=13284.427\,{{{{\rm{cm}}}}}^{-1}\). The y-axis shows the rate in arbitrary units (a.u.). The errorbars show one standard deviation statistical uncertainty.
