Ion imaging studies of the photodissociation dynamics of CH2I2 at 248Â nm

- Low translational energy release to I∗ (2P1/2) photofragments.
- Impulsive recoil of I∗ and CH2I products.
- Anisotropic angular distribution indicative of electronic state mixing.
- High internal excitation of CH2I fragments likely carried into CH2OO intermediates.
