Nakayama, K. Takahashi, Y. Matsumi Title: Quantum yield for hydrogen atom formation from H2O2 photolysis in the range 193-240 nm Journal/Source: Int. J. Chem. Kinetics, 37, 751-754, (2005) Data: Energy/Wavelength range: 193 - 240 nm Resolution: Temperature: 295 K Temperature dependence: no Pressure/Concentration: Phase: pH: Comments: 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. Author to whom correspondence should be addressed: (e-mail address):
