β¦ Synopsis
Hydrogen atoms produced by photodissociation of H202 using 193 nm laser light have been observed for the first time. The H atoms are detected by VUV spectroscopy. The yield is 12 rt 1%. The H atoms are produced by a one-photon process.

The photofragmentation dynamics of Hz02 at 193 nm have been analyzed by probing the OH products by Doppler spectroscopy Using laser-induced fluorescence. The excess energy (Eav = 4 17 kJ/mol) appears mostly as translational motion of the fragments with ft = 0.84. No vibrational excitation was observ
## Abstract Photodissociation processes of H~2~O~2~ in the range 193β240 nm have been studied by pulsed laser photolysis and laserβinduced fluorescence detection of H atom fragments at 121.56 nm.
