✦ 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.
