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
Gas Phase I2
I2 in Ar clusters
Bound B-state behavior
Dissociative A-state behavior
(note bare I2 still B-state behavior)
Dissociative A state
Long time-scale behavior
A-state vs B-state dynamics
Both pathways end up on A state, with lifetimes of micro- to maybe milli- seconds
