Journal ArticleDOI
Mass spectrometry of N‐nitrosamines
TL;DR: The preparation of a series of N-nitrosamines for carcinogenicity studies presented an opportunity to study mass spectral fragmentation schemes in detail, and aliphatic and alicyclic nitrosamines were generally characterized by molecular ions and loss of OH.

Mechanism and Structure in Mass Spectrometry: A Comparison with Other Chemical Processes
T.W. Bentley,R.A.W. Johnstone +1 more
TL;DR: In this article, the calculations of ionization potentials, molecular-orbital arguments used up in mass spectrometry are heavily dependent on assumptions regarding ion structures or fragmentation processes.
Journal ArticleDOI
Analysis of organophosphorus insecticides in biological samples by selective ion monitoring gas chromatography-mass spectrometry.
TL;DR: Gas chromatography with chemical ionization or electron impact mass spectrometry and selected ion monitoring provided a simple and sensitive method for measuring organophosphorus insecticides.
Journal ArticleDOI
Mass spectrometer as a probe in the synthesis of 2-substituted benzimidazoles
TL;DR: In this paper, a new synthetic approach towards the synthesis of 2-substituted benzimidazoles is developed based on the electron impact studies of N,N'-diacyl-1,2-benzenediamines under 70 eV conditions.
Journal ArticleDOI
Mass spectrometry of five classes of trityl compounds-loss of 12C from (C6H5)313CH
K. Darrell Berlin,R. D. Shupe +1 more
TL;DR: The mass spectra of 25 triphenylmethyl (trityl) substituted compounds have been recorded and a mechanism for the decay of the trityl cation is presented which is based upon retention of the α-carbon.
