Radiative and predissociative lifetimes of the A 2Σ+ state of OH

摘要: Lifetime measurements have been made on the A 2Σ+ state of OH by delayed coincidence technique in conjunction with an interrupted rf discharge through water vapor. Lifetimes are reported for rotational states up to K=29 and K=20 ν=0 ν=1 vibrational levels, respectively, unresolved levels ν=2. predissociation, previously predicted from relative intensity measurements, resulting a curve crossing repulsive 4Σ− state, was observed above K=23 ν=0, those K=14 ν=1, all These lifetime data discussed qualitatively terms electronic‐rotational perturbation matrices overlap integrals.
