Observation of b${}_2$ symmetry vibrational levels of the SO${}_2$ $\tilde{\mbox{C}}$ ${}^1$B${}_2$ state: Vibrational level staggering, Coriolis interactions, and rotation-vibration constants

G. Barratt Park, Jun Jiang, Catherine A. Saladrigas +1

The $\tilde{\mathrm{C}}$ ${}^1$B${}_2$ state of SO${}_2$ has a double-minimum potential in the antisymmetric stretch coordinate, such that the minimum energy geometry has nonequivalent S…
