Abstract

Additional plots of resonances for the quasi-bound levels of A2Delta and C2Sigma+ states of CH; ExoMol .states file for the ab-initio CH line list with additional columns containing total lifetimes and predissociation efficiency.

Supplementary data: C2Σ+state resonances The images in the following section are ordered by {v, J, e/f}. Each resonance is picked from across a thousand Duo output files based on quantum numbers assignments. The algorithm then uses a combination of the kmeans test to deal with misassignments of approximate quantum numbers (v, Ω) that helps select the largest cluster; we then prune the “outliers” within the cluster itself to zoom in on the resonance along the energy axis, which helps us get good distributions for a fixed number of bins. 1 2 3 4 5 6 7 8 9 16 17 18 19 20 21 22 23 24 25
