✦ Synopsis

Mass spectra of very large branched hydrocarbons containing up to 103 carbon atoms were studied. New and characteristic fragmentations at branching sites were identiÐed. 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 signiÐcance of these studies is that other techniques for structure elucidation (e.g. NMR) have limited utility for this class of compounds.

## Abstract Large multiply branched saturated hydrocarbons containing 67–103 carbon atoms (molecular masses 941.8–1446.8 Da) were analyzed by field desorption mass spectrometry (FD‐MS) with a double‐focusing mass spectrometer. FD‐MS was found to have detection limits in the 100 fmol range. The FD m
