Mass spectra of very large branched hydrocarbons containing up to 103 carbon atoms were studied. New and characteristic fragmentations at branching sites were identified. Medium-energy (~ 20 eV) electron ionization mass spectra were found to be most useful for structural characterization, tandem mass spectra giving important additional information. The significance of these studies is that other techniques for structure elucidation (e.g. NMR) have limited utility for this class of compounds.
