The ejection of hydrated electrons from 266-nm laser-photoexcited solutions containing Cu(NH3)+3, CuCl3/2-, or CuBr3/2- Occurs through two pathways on the nanosecond time scale: a prompt ejection (τ < laser pulsewidth), and a delayed ejection (τ > laser pulsewidth) which follows a first-order rate law. This behavior is consistent with electron ejection from two excited states: the primary CTTS state, and longer-lived triplet species consisting of an exciplex and its precursor. The quantum yields for both prompt and delayed ejection are quite high, in the 0.15-0.4 range.
