Presentation Transcript

  1. I2 in Argon Clusters Pump: varied from 480-700 nm Probe: mostly 307 nm Laser induced fluorescence: monitored peak at 400 nm and 342 nm

  2. Gas Phase I2 I2 in Ar clusters probe pump

  3. Bound B-state behavior

  4. Dissociative A-state behavior (note bare I2 still B-state behavior) Geminate recombination Dissociative A state

  5. Long time-scale behavior B state B-state excitation predissociation Geminate recombination A state

  6. A-state vs B-state dynamics Both pathways end up on A state, with lifetimes of micro- to maybe milli- seconds
