Ion–molecule reactions of CoAr₆⁺ with nitrogen oxides N₂O, NO, and NO₂: measuring absolute pressure by shock-freezing of the collision complex
A new method to determine the absolute pressure in an ultra-high vacuum apparatus is tested using ion molecule reactions with CoAr₆⁺. In a collision with a neutral reactant, the complex between Co⁺ and the collision partner is stabilized by evaporation of argon atoms. If CoAr₆⁺ reacts with collision...
