Abstract

A new series of hypervalent radicals has been generated by neutralizing a fast beam of NH₄(NH₃)_n⁺or CH₃NH₃(NH₃)_n⁺ ions in the electron transfer reactions NH₄(NH₃)_n⁺+ K (or Na) → NH₄(NH₃)_n* + K⁺ (or Na⁺) (for n = 0–2) and CH₃NH₃(NH₃)_n⁺+ K → CH₃NH₃(NH₃)_n* + K⁺ (for n = 0–1). Mass spectra of the reaction products have been obtained by the technique of charge stripping with NO₂as collisional ionization gas. New results on the stabilities of CH₃NH₃, CH₃N₂H₆, N₃H₁₀,and their deuterated forms are presented. The effects of internal excitation on the decomposition pathways of the radicals are discussed. These species constitute a novel class of radicals with ionization energies estimated to be in the range 3 to 4.5 eV.
