Rowley, J.C. Moessinger, R.A. Cox, R.L. Jones Title: The UV-visible absorption cross-sections and atmospheric photolysis rate of HOI Journal/Source: J. Atmos. Chem., 34, 137-151, (1999); doi:10.1023/A:1006210322389 Data: diagram, table Energy/Wavelength range: 280 - 494 nm Resolution: Temperature: 298 Temperature dependence: no Pressure/Concentration: Phase: gas pH: Comments: The UV-visible absorption cross-sections of HOI have been recorded over the wavelength range 278-494 nm and at 298 K following generation of HOI in the gas phase using laser flash photolysis. The HOI spectrum recorded exhibits 2 broad absorption maxima of sigma = 3.99 × 10-19 cm2 and sigma = 2.85 × 10-19 cm2, centred at 338.4 nm and 404.8 nm respectively.
