Abstract
An exact quantum mechanical theory is employed to treat predissociation process of the A2Σ+ state of OH. The widths and positions of the lower (v= 2 and v= 3) rovibrational levels are calculated. Energy shifts of the resonances from the zeroth order (pure Hund'scase (b)) positions are shown to be small for N ≤ 10, indicating that the A2Σ+ state can be described as case (b) very well for low N. Due to the differential interactions of the A2Σ+1/2 and A2Σ+-1/2 states with X2Π and 22Π states, small splittings between the F1 and F2 levels are predicted. Calculated lifetimes of the resonances agree with experimental results reasonably well.
