Field desorption mass spectra have been recorded of n-dotriacontane, n-tetracosanoic acid and hexadecyl hexadecanoate as representatives of long straight-chain alcohols, acids and esters respectively. Molecular or quasimolecular ions were formed almost exclusively with fragmentation at a low level.
