Concurrent Ion–molecule Reactions Leading to the Same Production

Abstract

Seven of the major secondary ions in the high-pressure mass spectrunl of cyclopropane have been studied. A method has been developed for studying concurrent ion-molecule reactions and it has been shown that four of the secondary ions are the products of more than one reaction. Cross sections for the separate reactions are reported. The appearance potentials of the major primary ions in the mass spectrum of cyclopropane have been measured:

Concurrent ion–molecule reactions. III. Reactions in mixtures of HCl and HCN with D2 and CD4

“…Reaction [2] was also studied a t thermal ion energies by the pulsing technique. Typical plots of IH,cN+/IIIcN+ as a function of delay time are shown in Fig.…”
