Recent mass spectrometric studies of species and processes relevant to the chemistry of atmospheres are reported. New species have been detected, including HO3; a stratospheric reservoir of OH radicals; the [H2O+O2-] charge transfer complex, central to the atmospheric photonucleation theory; and the OSOSO oxide and its cation, likely present in the Io's atmosphere, As to ionic processes, a new route to tropospheric N2O in air ionized by lightning and coronas is reported, as well as the complex chemistry promoted by ionization of ozone/freon and ozone/carbonyl sulfide mixtures and the formation of O-5(+), relevant to the problem of O-18 excess in stratospheric ozone.

Abstract

New species have been detected, including HO3; a stratospheric reservoir of OH radicals; the [H2O+O2-] charge transfer complex, central to the atmospheric photonucleation theory; and the OSOSO oxide and its cation, likely present in the Io's atmosphere, As to ionic processes, a new route to tropospheric N2O in air ionized by lightning and coronas is reported, as well as the complex chemistry promoted by ionization of ozone/freon and ozone/carbonyl sulfide mixtures and the formation of O-5(+), relevant to the problem of O-18 excess in stratospheric ozone.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
