Ultra - violet absorption cross sections of isotopically substituted nitrous oxide species : 14 N 14 NO , 15 N 14 NO , 14 N 15 NO and 15 N 15 NO

The isotopically substituted nitrous oxide species 14N14NO, 15N14NO, 14N15NO and 15N15NO were investigated by ultra-violet (UV) absorption spectroscopy. High precision cross sections were obtained for the wavelength range 181 to 218 nm at temperatures of 233 and 283 K. These data are used to calculate photolytic isotopic fractionation constants as a function of wavelength. The fractionation con...
