Ion‐molecule reactions of low energy (0–0.15 ev) CHN+ and CH3N+ are shown conclusively to follow a hydrogen atom abstraction mechanism of the type, XH++YH→XH2++Y. These reactions are presumably bimolecular being first order with respect to each

The retarding potential difference method has been used to measure ionization efficiency curves of CH3X+ (X=H, F, Cl, Br, I), CH3+, and X+ from methane and the methyl halides in a time‐of‐flight mass spectrometer. Discontinuities between linear s

Two techniques were used for the elucidation of ion‐molecule reaction mechanisms in the alpha radiolysis of C2H4 in the new alpha‐particle mass spectrometer. The corresponding variations in the percent of primary, secondary, and tertiary ions ove

A number of new metastable transitions have been identified in the mass spectra of n‐butane and i‐butane. The appearance of various metastable transitions was discussed in terms of the quasi‐equilibrium theory of mass spectra and the energetics

The mass spectrum of methane has been investigated in the pressure range 1×10—7 to 5×10—5 mm of Hg. A number of diffuse peaks were observed at nonintegral masses. These arise from dissociation of various ionized methane fragments on collision w

The dissociations of CO+ and CO++ ions by ion‐molecule collision have been investigated with a mass spectrometer. CO+ dissociates into C+ and O, or C and O+, depending upon the energy of the parent ion. The predominant ion resulting from dissociati

The principal positive and negative ions in the mass spectra of formic acid and deuteroformic acids are reported. It is shown that the positive ions of mass 45 (CHO/sub 2/sup +/), 29 (CHO/sup +/), and 13 (CH/sup +/) are formed by reactions involving

Two high transmission electron-bombardment ion sources, based on a principle of electrical rather than mechanical ion collimation, have been developed and tested with a 6 in. radius-sector type of mass spectrometer. The new ion sources had a measured
