Rotational energy level population

WebThe rotational ground state population of HD+ ions is derived by the results of the state-selected [1+1'] resonance-enhanced multiphoton dissociation (REMPD) [Fig. 1(c)] combined with the rate equations modeling the evolution of the rotational state populations due to BBR coupling.
