Abstract: Study of the low-voltage (10 ev) spectra of a series of aliphatic ketones with regard to the a-cleavage process (I-.+ a+ b) reveals that the smallest alkyl radical is preferentially eliminated, contrary to the situation existing at 70 ev. A series of aliphatic Schiff bases at low voltage behave in a similar fashion. Aliphatic ethers lose an alkyl radical by a-cleavage (11- + c) in preference to a methyl radical but when a choice between two alkyl radicals (ethyl ...
