The appearance potential of the CH2Cl+ ion has been measured from methyl chloride, dichloromethane, bromochloromethane, and ethyl chloride. The results lead to ΔHf(CH2Cl+) = 230 ± 3 kcal/mole. The heat of formation of CHCl2+ is estimated to be 215

A series of alkylphenylketones has been examined. Whenever the alkyl chain is three or more carbon atoms long, the well-known McLafferty rearrangement occurs with elimination of the elements of a neutral olefin. The further fragmentation of the ion f

A pulsed ion source has been constructed for use with a magnetic-deflection mass spectrometer. With this source the time between ion formation and withdrawal for analysis can be controlled and varied in a known manner. The design and operating charac

A study of the shape of metastable peaks observed in a mass spectrometer was carried out. The shape of the peak is related to the distribution of kinetic energies released in the decomposition. For Gaussian‐shaped metastable peaks the kinetic‐ene

A ratio‐plot method, whereby the contribution of concurrent ion—molecule reactions to the same product ion may be estimated, has been applied to the study of the formation of the XD+ ion in X—CD4 mixtures for X=CO, N2, and CO2. It is shown that

Mass spectra of 2-methyl-5-chloro-3-N-ethyl-benzothiazolium iodide and labeled counter-parts are discussed with particular emphasis on the loss of ethylene from the moiety produced by thermal elimination of HI from this salt. This process demonstrate
