Abstract

Photodissociation processes of H~2~O~2~ in the range 193–240 nm have been studied by pulsed laser photolysis and laser‐induced fluorescence detection of H atom fragments at 121.56 nm. The quantum yield values for H atom formation at 295 ± 2 K have been determined to be 0.20 ± 0.03, 0.038 ± 0.008, 0.029 ± 0.003, 0.015 ± 0.006, 0.007 ± 0.002 at 193, 207, 210, 220, and 230 nm, respectively. At 240 nm, only the upper limit value of <0.002 has been obtained. © 2005 Wiley Periodicals, Inc. Int J Chem Kinet 37: 751–754, 2005

## Abstract The primary quantum yield of H‐atom production in the pulsed‐laser photolysis of hydrazine vapor, N~2~H~4~ + hν → H + N~2~H~3~, was measured to be (1.01 ± 0.12) at 193 nm relative to HBr photolysis, and (1.06 ± 0.16) at 222 nm relative to 248‐nm N~2~H~4~ photolysis, in excess He buffer
