Metastable and collision induced Coulomb explosion of doubly charged ammonia cluster ions

A continuous neat ammonia cluster beam was ionized by electron impact ionization, then analyzed by a tandem triple quadrupole mass spectrometer. Metastable Coulomb explosion was observed for the {NH3}51Hx=0,1,22+ and the {NH3}53Hx=0,1,22+ cluster ions. Coulomb explosion was observed in larger doubly...

Description
Summary:A continuous neat ammonia cluster beam was ionized by electron impact ionization, then analyzed by a tandem triple quadrupole mass spectrometer. Metastable Coulomb explosion was observed for the {NH3}51Hx=0,1,22+ and the {NH3}53Hx=0,1,22+ cluster ions. Coulomb explosion was observed in larger doubly charged cluster ions activated by low energy collisions with argon gas.
