Abstract

The 257 nm photochemistry of CD3I adsorbed on MgO (100) has been investigated. The photofragments ejected along the surface normal were probed using resonantly enhanced multiphoton ionizationspectroscopy coupled with time??of??flight mass spectrometry. Methyl radicals and atomic iodine fragments in both the ground I (2 P 3/2)≡ I and spin–orbit excited I (2 P 1/2)≡ I* states were observed as direct photofragments produced at the surface. ...
