NOO Peroxy Isomer Exposed with Velocity-Map Imaging

Autor: Stephen Gibson, Steven Cavanagh, Benjamin Laws, Brenton Lewis

Publikováno v: The journal of physical chemistry letters. 8(18)

The chemistry of NO2, a key atmospheric trace gas, has historically been interpreted in terms of the C2v isomer ONO, with the peroxy isomer NOO only postulated to be stable. In this work, a velocity-map-imaged photoelectron spectrum of the nitrite an

The threshold photoelectron spectra of H2O and D2O have been recorded over the ionization region (12–40 eV) under high-resolution conditions using synchrotron radiation. Extensive vibrational ‘filling-in’ is found in the Franck–Condon gap reg
