New cluster species of the type (HCN)(m)(NH3)(n)H+ with m up to 4 and n up to 7 alongwith (NH3)(n)H+ species are observed using mass spectrometry, on the reaction of carbon vapor with jet-cooled NH3 in admixture with helium. ...

Vapor-phase clusters from ethanol-water liquid mixtures of varying compositions, generated by sampling the binary vapor in equilibrium with the liquid mixture, were examined with the aid of a time-of-flight mass spectrometer. ...
