The ion kinetic energy (IKE) spectra of nonan‐4‐one, 7,7‐d 2 ‐nonan‐4‐one and 1,1,1‐d 3 ‐nonan‐4‐one have been recorded and interpreted. The various fragmentations observed in the IKE spectra have been confirmed and some new fragmentations found by carrying out high voltage scans with the magnetic field set successively to collect ions at each mass to charge ratio throughout the mass spectrum. Several new fragmentation modes have been discovered, and their significance is discussed.
