Abstract: | Organocyclosiloxanes of various chemical structures were studied by mass spectrometry using different ionization methods.
The electron ionization mass spectra contain no peaks of molecular ions, and the main fragment ions are formed due to complicated
rearrangements in a molecular ion, which provides no comprehensive view about the molecular structure. The desorption spectra
exhibit peaks of quasimolecular and fragment ions, which characterize both molecular weights and chemical structures of the
compounds under study.
Dedicated to Academician G. A. Abakumov on the occasion of his 70th birthday.
