The mass spectrometric fragmentation behaviour of pyridazine and four monosubstituted derivatives containing a phenylalkyl side-chnin (3-and dbenzylpyridazine, 3-and 4-Q-phenylethyl)pyridazine) was investigated. In the electron impact ionization mass spectra of the hubstituted compounds abundant [ M

β¦ Synopsis
The electron impact and methane chemical ionization mass spectrometry of fifteen trisilanes and trisiiloxanes containing various substituents was studied with the aid of exact mass measurements and metastable ion analyses. Migration reactions of the two kinds of compounds are discussed.

The electron impact induced fragmentations of 24 tetrahydropyrane ethers of different types of alcohols were studied by exact mass measurement and metastable ion analysis. The most characteristic features of the spectra were associated with the tetrahydropyrane ring. As the size of the molecule incr
The mass spectra of unlabelled and specifically labelled triterpenes and derivatives were recorded using thermospray liquid chromatography (TSP-LC) and electron impact (EI) ionization. These mass spectra were used for the development of assays to characterize the products from the in vitro oxidative
The electron impact-mass spectra as well as the complementary chemical ionization-mass spectra (with the reactant gas ammonia) of various structural types of sesquiterpene lactones isolated from Achillea species are discussed in respect to the important information either gained by fragmentation pat
