Mathematical expression for the O (¹D) quantum yields from the O3 photolysis as a function of temperature (230‐320 K) and wavelength (295‐320 nm)

The exact quantum yield of the O (¹D) formation from the ozone photolysis in the UV range 295‐320 nm is important for aeronomic calculations, since O (¹D) is the primary source for OH radicals in the troposphere. Recent O (¹D) quantum yield determinations at 230, 268, 298 and 320 K are summarized and an analytical expression is derived which relates the quantum yield of O (¹D) formation as a function of wavelength and temperature.
