The ion molecule reactions have been studied with the instrument which consisted of two mass spectrometers. Samples were used He+, Xe+, N2+, CO+ and C2H4+ as the primary ions(bombarding ions), and n-butane as the secondary sample. In this instrument the path of the primary ions met at right angles with the path of the secon dary, and that the secondary ions were seperated with the double focussing mass spectrometer, then the ions produced through the recombination of the primary ions and n-butane were scarecely observed. In the case of inert gas ion(He+, Ar+, Xe+)bombardment, the mass spectra of n-butane showed some characteristic feature, or, the intensity of molecular ions and the number of fragment ion peaks were decreased in inverse proportion to the mass number and momentum of the primary ions. And in the case of same mass number ion(N2+, Co+, C2H4+)bombardment, the mass spectra of n-butane were not affected by the mass number of the primary ions, but they were affected by the chemical characteristics and the size of the primary ions more dominant.
