Description
Summary:N3O+ ions prepared in the source of a mass spectrometer under low-pressure conditions are submitted to neutralization by collisional electron transfer, leading to the observation of the novel N3O oxide. [Display omitted] ► The study reports the positive detection in the gas phase of the novel azido oxide N3O. ► It has been prepared by collisional electron transfer to the N3O+ ion and observed on a microsecond time scale. ► The oxide has been assigned a minimum lifetime of 0.7μs and an open-chain structure of NNNO connectivity. ► The study examines the role of excited species in the formation of covalently bound ions suitable to neutralization. The new nitrogen-rich oxide N3O has been detected in the gas phase by mass spectrometric experiments. The radical has been assigned a minimum lifetime of 0.7μs and an open-chain NNNO structure in the quartet state. Structures and energies of the N3O+ precursor ion and the N3O radical have been investigated by ab initio calculations.
