Vibronic branching ratios for nearly-closed rapid photon cycling of SrOH

Zack Lasner, Annika Lunstad, Chaoqun Zhang +2

The vibrational branching ratios of SrOH for radiative decay to the ground electronic state, $X^2{\Sigma }^{+}$, from the first two electronically excited states, $A^2\Pi$ and $B^{2}Σ^{+…
